I must agree here, and am only doing the ultrasound as a possible "least invasive" step in our journey to find what is truly ailing Valentino. I am actually researching different veterinarians right now in hopes that I can find someone close to consult. As I said, I am starting to see that this is not my vet's expertise and have found that you shouldn't go against gut feelings when you get them, especially when it is dealing with the health of a (very) loved one...
