Kathy very sorry about the lose of your Doxi. We were grateful to be OWNED by our Doxie Pookie many years ago. Actually hubby and I decided to watch some old family VHS videos and there was Pookie in every video with the kids. Our family was lucky to have him with us for 16 years. Was very hard to let him go but now these memories of our first dog as a family are the best.
We have a almost 17 year old Chihuahua who was just diagnosed with enlarged heart. However vet explained that in small breeds it is very common to have Mitral Valve disease which she has. Symptoms with most only show up in later years. Her X-rays show the enlarge heart. No lung edema which is great. Doxies are also prone to mitral valve disease. Maybe it wasn’t the dog food but just genetics.
What is Myxomatous or Degenerative Mitral Valve Disease?
Canine myxomatous or degenerative mitral valve disease (MMVD) primarily affects older, small to medium size dogs, although any dog can be affected. Degenerative changes thicken the valve, causing it to leak. When the disease and leakage progress, the heart enlarges. Predisposed breeds include Cavalier King Charles Spaniels and Dachshunds and other breeds – although the genetics are being investigated, the disease is very common in small breed dogs as they age. Though many dogs are affected in their later years, only about 25-50% of those with MMVD experience clinical signs of congestive heart failure (CHF, or uid build-up within the lungs).
I think I’ll share this also in main forum to let others know DCM can also be caused by other things then diet.
