Pageturner

I will just throw the facebook page out there. Taurine-Deficient (Nutritional) Dilated Cardiomyopathy. Most of the admin and mods are Veterinarians. Hope you are able to get to the bottom of Merlin's issue and back to normal!

What kibble are you feeding? I know the grain free/heart disease link did not appear to be taken very seriously here, but it is real. No, it does not affect every dog eating grain free kibble but it has affected all breeds, including mixes, and all ages, some under a year old. An echo of the heart is the only way to diagnose. A vet listening to their heart may conclude it is normal, often the first sign in a healthy appearing dog is collapse. Just throwing it out there if you are feeding a grain free diet as something else you may want to look into.
