just had my 8 yr dog cody yearly check and he has lost 1 kg over 2 yrs he is now 7.5 kg eating and drinking fine. Vet did urine dip stick it was fine for diabetes but had protein in it and suggested he has more in depth urine test at the lab. She worried me a bit because she was talking about a special diet if protein is too high. She did say as they get older they do get a few urine problems as humans do. Has anyone else had similar problem
