This morning my two American Brittany dogs (Fae age 1 and Piper age 2) came inside after being outside in our fenced yard. We live in a rural area. Fae vomited her breakfast but she sometimes does that if she eats too fast. Before we knew all that was going on, our Pyr mix Gus at some of her vomit and then he vomited. After they came in, both girls started licking and biting at their feet - all four. Thinking they had ants biting them, put them in shower and washed their feet - no signs of ants. They continued to bite and chew different feet. Examined feet for cacti or other sharp things and could not find anything. Both girls continued to be very restless and chew feet. I gave them a dose of Ant Crud 6C and they seem to calm a little and go to sleep but were restless and moving around on their beds. My daughter went to check the fenced area for ants, etc and she saw a coral snake. We have no idea if the dogs were bitten. We cannot find bite marks or swollen area. Recently found a little blood on Piper's foot but it could have been from her chewing. We just moved and I do not have a vet yet - very hard to find a holistic vet sadly. I called a local vet and was told that it would be obvious if they were bitten - swollen, pain, lethargy. I gave them two doses of Lachesis 30C and Elaps Corrallinus 30C (I am a Homeopath). Is it obvious when they are bitten by coral snake? Some reading on web indicates might not be so... I am concerned to go to an emergency vet and if they prescribe anti-venom, esp since we are not sure if they were bitten. Any experience with this? Thanks so much!
