I used this nutritionist two years ago when my yorkie was diagnosed with kidney failure and pancreatitis:
Lisa P. Weeth, DVM, Diplomate ACVN
works out of Redbank veterinary hospital in Red Bank NJ
732-747-3636 is the hospital telephone number
She developed homemade recipes for my dog since she couldn't eat any commercial dog food.
Jessie has since passed away at almost 15 years old but she was kept alive for almost a year with a good quality of life with the diet and on fluids.
