I almost put him down the other day, but he suddenly got better at the vet's office and started eating. Currently I feed him the Hills Kidney wet food diet and chicken. I was giving him vetmedin for his heart disease, but quit giving him the meds as he seems to do better without them (at least as far as his kidney's go) Any ideas for supplements or foods? I'm thinking about giving him some potassium. Any advice to keep him for as long as I can provided he has some quality of life would be wonderful. Thank you!
