We did the full range of tick tests and they all came back negative. We did an ultrasound earlier today and the internist said that it looks like Wolfie has renal disease due to renal dysplasia (not formed properly) or poor vascularization (blood supply) in the uterus. This diagnosis is driven by the fact that Wolfie is only 6 months (his weight today was 53.7lbs). His urine is very dilute and he has been prescribed Azodyl, which is a new product to lower phosphorus and kidney values. The vet called it "dialysis on a pill". He is supposed to take 3 pills a day for the next 20 days to see if his urine gets any less dilute. Also, the internist suggested that we replace about one third of the protein in his food with either rice, pasta or veggies. I will start by giving him some beets, pumpkin and potatoes over the next few days. He has been on Proplan thus far as that is what he had been eating at the breeder's but I will switch him over to the holistic types food brands (I bought the Canine Caviar to start with). I fervently hope he likes that better as he has been turning away from Proplan completely these last few days.
