Diet: Currently on Royal Canin Urinary S/O and Gastro (See info below) Looking to switch to real food diet
Vax: Vaxinated and on flea tick, as I didn't know better at the time, has been on some rounds of antibiotics before

BEAM
Behavior

Since March: plays a little but stops after a few minutes, is more itchy, eyes are more watery, yaws more, licks lips, licks the bed sheets at night, bites paws, more unsettled (moves around more than usual, before getting comfortable,) snores, gags, coughs, makes a honking sound, makes small huffing/coughing sounds after running/playing and longer walks and makes little noises sighs/small moans, when going to lay down – recent vet said this is due to indigestion, would you agree?

Energy is good.
Appetite is good. He always wants to eat, some days less, but mostly he eats.
Mood, overall good, but sometimes he wants to be alone and goes under the bed (normally wants to be with us, all the time) He’s a trouper, but I know he’s off and sometimes doesn’t feel well.


Hello,
This is a little long, but please bear with me as the issue is twofold, and I am at a loss.

I am a member – I have searched the library and forum, watched most of the videos on the YT channel, and seen 4 different vets/integrative vets, but I am receiving conflicting information and still have questions/concerns.

For most of his life, he was on a better, cleaner kibble, no grains, with chicken being the first ingredient with minimal other ingredients. I stopped being able to get this food, so I switched him to another brand, which I cannot recall, but was similar.

About 6 months ago, a couple of months after being on the new food, he had an episode where he was urgently needing to pee, often, and with blood. The vet tested his urine and found that he had oxalate crystals. They gave him antibiotics to treat it and told me he had to be on the prescription Royal Canin Urinary S/O diet. I was not impressed with the ingredients, and the fact that salt is the “helping” factor, didn’t sit well with me. I asked for alternatives, and they told me there weren’t any. I asked about making food, or going raw, and they got irritated with me and told me not to.

I called a few vets, saw another, but I got the same info.

He went on the prescription Urinary SO food in June, with no new episodes happening until November. He had an episode where he started having bloody diarrhea, with mucus, and had to go every couple of hours for about 12 hours. He was very clingy and was not feeling well. I brought him to the vet and examined the poop and told me it was a “small intestine issue” there was a “bacterial imbalance,” They put him on antibiotics, some probiotics and told me to switch his food from the Royal Canin Urinary S/O to the Royal Canin Urinary S/O + Satiety as this could have more fiber and help the digestive tract.

At the beginning of March, he had a 2nd episode where he threw up 3 times over a couple days. Twice food and the third, blood - he did not want to eat that morning. He eats dry food with some wet food mixed in as he won’t eat just dry, alone. I had run out of wet food, so I steamed him some carrots and peas, which I thought would be okay, as they are in his canned food, but perhaps that upset his stomach? I went to get him his wet food, and he was fine after.

A few weeks later, at the beginning of April, his latest episode, he started having diarrhea with mucus. He went out every two hours for 12hrs each time with diarrhea, at first no blood, then after a while, blood. The next day, the diarrhea was less frequent, but he started throwing up bile with some blood. Since this was the 2nd episode in a month, I was concerned so I brought him in. They suspected Addison’s but it's not, they did blood - everything looked normal and they did an ultrasound - nothing of concern but saw some irritation in the digestive tract. He was diagnosed with Gastroenteritis. I asked the doctor is he wanted to test his poop to see if it was another bacteria, he said no. (Looking back, maybe I should have pushed that?) I was sent home with probiotics, and a bunch of other things, and told to give him Royal Canin wet Gastro food for 5 days until things returned back to normal, then to return back to his regular food.

I went to see an integrative vet, who is also a nutritionist, in hopes for some other alternatives. She told me to avoid foods high in calcium, raw food as it has bones with are high in calcium, as they can all contribute to Oxalate crystals. She also gave me a long list of foods (mostly veggies, that have oxalates to avoid.) I have read about others who have been given something natural and their pets never had crystals again. She suggested “Corn Silk” and “Couch Grass” and told me I could buy tincture (which I don’t want to do as they have alcohol and I don’t think that’s good for them, right?) or she said I could buy dry herbs from online and grind them up and put them in his food or steep them and add the water to food or have him drink if he would. She told me adding water to his food is imperative and the thing that will help the most.

I go back and forth from Montreal and Toronto. This is only integrative vet I could find and she was 2 hours away from me. When I get back to Toronto, I will try and look for others there, but the ones I have found so far are not taking patients right now or there is a very long wait list.

Since the episode in April, his poop is now solid, but often has some thin string like, (believe mucus?,) and sometimes has darker spots in it (digested blood?)

Looking for more support, please. I love him so much, I just want to do right by him.

Questions:
1. Do these “high oxalate” foods really contribute to oxalate crystals? I’m getting conflicting info from vet to vet

2. For dogs with Calcium Oxalate crystals:
  • Do bones and raw food with bones in them need to be avoided as they have calcium?
  • Does that include bones like marrow to chew on for teeth health?
  • I saw Vit C should also be avoided.
  • In the webinar I saw in the library, it says low carbs, high protein, and lots of vegetables (don't most veg have high oxalates?,) but the integrative vet told me to use lots of carbs and watch out for vegetables - what's the right thing to do?
  • Suggestions on what to feed, please?

3. Please provide suggestions on supplements to break up crystals and stones, and where to get? I've heard of Chanca Peidra?

4. Please provide good, trusted holistic vets in Montreal/Toronto or even in Canada that is still taking new clients.

THANK YOU
@Dr. Jeff @Dr. Christina

From a human perspective, I know people with oxalate stones where reduction of oxalates in the diet has helped prevent future stones. The main source of oxalates is plants. Some have higher oxalate content than others. By cooking them thoroughly the oxalates will be reduced but they are still there. Calcium actually binds to oxalates and prevents oxalate formation in the body. Therefore, feeding a low calcium diet combined with high oxalate foods would be disastrous in my opinion. I see no need to reduce calcium. It should be fed as part of a balanced diet and not overdone just like anything else. I personally believe raw meaty bones are the best source of calcium vs synthetic supplements. The only reason I can think of as to why bone would be reduced is in the case of severe kidney disease because bones are very high in phosphorus. I think feeding a fresh food diet with low or better yet no oxalate foods, high in moisture content and with appropriate levels of calcium and other ingredients could be helpful.

Thank you Joanna, for sharing so much detail about your precious boy. Your love, dedication, and persistence shine through every word. 🩵 You are absolutely on the right path, even if it feels confusing at times — advocating for him, seeking deeper answers, and trusting your inner knowing are core parts of the healing journey we emphasize at Holistic Actions! and through the Path to Pet Wellness.
receiving conflicting information
I'm sorry to hear this. Unfortunately, it is the essence of the problem with the current medical/vet paradigm which is based on symptoms as "problems" to be fixed.

With that being said, I'm replying from a fundamentally different perspective than that which is taught in vet school. But it is informed by all parts of the great physiologically based paradigm that we learn as vets.

Let’s walk through this step-by-step together:

Trust the Body’s Wisdom: Symptoms Are Communications, Not Mistakes

From a Path to Pet Wellness perspective, everything you're seeing — the crystals, the digestive flare-ups, the lip-licking, the honking sounds — is your pup's body doing its best to stay in balance in a challenging environment. These are messages, not signs that his body is not operating optimally.

His symptoms point to underlying imbalance (susceptibility) rather than isolated "dis-eases." By supporting his body's vitality and rebalancing his inner terrain — especially the microbiome and inflammatory pathways — you can help him heal at the root.


Understanding Susceptibility: What Set the Stage

You identified key stressors that contribute to susceptibility:

Past kibble diets (even the better ones)

Anti-biotics

Vaccines

Flea/tick chemicals

Prescription foods

Each of these, while sometimes necessary, can subtly or significantly disrupt gut microbiome balance, immune regulation, kidney function, and overall energy flow.

The goal now is not to fight the symptoms, but to support his body in restoring normal energy and information flow (core Path to Pet Wellness principles).

Healing Foods and Practices (as informed by Anthony William)


Oxalate foods are not the root cause of crystal formation. It's chronic stress from various sources like toxicants (such as heavy metals, pesticide residues) that overwhelm elimination pathways.

Raw fruits and veggies are healing — even those with oxalates. It’s not the oxalates themselves that are the problem. It's the body’s weakened filtration and detox systems.

Avoiding fresh foods like meats and even fruits and vegetables could slow healing. Instead, build resilience by supporting detox pathways gently.

Healing focus:

Hydration is critical — extra water in meals is excellent. If you do nothing else right now, starting structured water, which can help every cell function better, is key. Here's more info:


Fresh fruits (especially wild blueberries, pears, apples, and melons) gently detox the kidneys and liver.

Healing veggies like celery, cucumber, lettuce, and zucchini are powerful support (not the problem!).

Minimize high-fat, high-salt, highly processed foods (like prescription kibble).

Avoid unnecessary supplements with synthetic ingredients (some vitamins like C ascorbic acid can aggravate the situation because they're not from whole foods).

Corn silk tea, couch grass infusion (glycerin-based if tinctured) are excellent! Try to minimize alcohol tinctures.

4. Answers to Your Specific Questions

Do high-oxalate foods cause crystals? No. It's the body’s impaired ability to handle metabolic waste. Strengthening the liver, kidneys, and gut microbiome is the priority.

Do raw bones/raw meats need to be avoided? Not necessarily. Heavily calcified, dense bones could contribute to mineral imbalance if the elimination pathways are weak.

I use Fiber Detox in my practice to help the detox process:


Soft, cartilaginous bones like chicken necks, sardines, or gelatin-rich broths may still be appropriate once he’s stable.

Hard marrow bones for chewing can sometimes cause micro-damage to teeth in small dogs anyway, so I’d prioritize softer chews and dental support.

Should you avoid Vitamin C? Whole food Vitamin C (like from fruits or camu camu powder) is healing.

Low carb/high protein vs. high carb/low oxalate? Neither extreme is necessary.

A balanced fresh food diet rich in hydrating fruits and veggies, moderate protein, and small amounts of healthy fats (like coconut oil, flax) is the way forward.

Focus on easy-to-digest real foods. (Think blended soups, lightly steamed veggies, and fresh fruit purees.)

Supplements to Support Healing

Chanca Piedra: Excellent for supporting kidney stone dissolution. A glycerin-based tincture or fresh tea form is safest.

Lemon balm, licorice root, burdock root, and wild blueberry powder: Help cleanse and protect kidneys and liver.

Probiotics: Rotate strains to rebuild his microbiome.

Humic and Fulvic minerals: Help remove environmental toxins safely.

I can help you find trustworthy brands if you'd like!

Holistic Vet Suggestions

Toronto:

Dr. Janet Tobiassen – Holistic vet consultations (may have a waitlist but worth trying)

King West Vets (Dr. Ellen Kinzl, holistic-friendly)

Montreal:

Clinique Vétérinaire Integrative de Montreal (Dr. Marie-Claude Morin)

You might also explore working with a virtual holistic vet for support while waiting for local options to open up!

Practical Next Steps

Perhaps transition slowly from Royal Canin to fresh food: start by adding small amounts of steamed zucchini, cucumber, celery into his meals.

Keep hydration high: add structured water, bone broth (low-fat, no salt), coconut water (unsweetened), and water-soaked food.

Support emotional balance: yawning, lip-licking, paw-licking often reflect gut-liver stress and emotional strain. Calm environment, regular schedules, gentle body massages all help.

Watch BEAM carefully: Changes in Behavior, Energy, Appetite, and Mood will guide you more reliably than tests alone.

Stay confident: The body is designed to heal when we remove obstacles and provide what it needs.

Good luck! Please keep us updated.

Thank you, @Dr. Jeff You are so kind. I really appreciate your prompt reply and information. I am so worried about him.

Your response is a little different from the response I saw another moderator respond to someone else's post on oxalate crystals, and is a little different from a video I watched in the library, where it says to avoid ox. foods

So sorry to ask more questions, but I am super overwhelmed. I promise I won't ask anymore after this!
  1. Is your fiber detox available in Canada? I have had some issues with the border not letting US supplements through. If not, any similar products you suggest, please?
  2. Yes, if you could please advise on trustworthy brands, for the other supplements you mentioned, I'd so appreciate that! Thank you for the offer
  3. I will start incorporating some veggies in the food and doing structured water.
    1. At this time, I am not able to fully cook his meals, as I am out of town and staying with a family member. Do you have any recommendations on fresh food, I could purchase? Is it too soon to go freeze-dried or raw? I've checked many sites, and they all have bones and some high-oxalate foods in them. Do you think he would be okay on those, given I "soup them up"? Or, too soon/risky?
    2. I checked out the thread for Structured Water - sorry, I am confused, is structured water just chia seeds in water? What is the ratio? Should it be more liquid or more gel? Or is there a machine to buy? I have a Berkey, does that work?
  4. And based on what you said above, do I necessarily need to avoid calcium? Is calcium iodate the same as calcium?
  5. You mention avoiding high fat, and to do low protein but isn't chicken, beef - meat in general - high fat and high protein? And doesn't the meat comprise the majority of their diet? I think I saw that in the 101. What is considered low protein, please?
  6. You mentioned a balanced diet, if I used a recipe builder website to help me formulate cooked recipes, they add their supplement of vitamins to make it balanced, so you need to buy their product, to make it balanced. How do I ensure that I am balancing them/ or that their product is okay? Do you recommend any? example: Recipe Builder | Hilary's Blend
  7. Thank you for your practitioner recommendations! In case you wanted to update your directory:
    I can't seem to find Dr. Janet Tobiassen's contact info or clinic. There is little info on her
    Dr.Ellen Kinzl, if the same Dr, is now at Canary District Animal Hospital
    Clinique Vétérinaire Integrative de Montreal does not seem to exist anymore. I found a Marie-Claude Morin - she is an acupuncturist, not a vet, I believe
Thank you a million. I appreciate you so much

Yes, my reply is based on a different perspective than you may nave otherwise received.

To reduce your overwhelm and address your other questions, you may want to set up time either for an HMDM call with me or Dr. Christina or schedule a full evaluation with a vet homeopath.
