My Totoro (name of my chin) has been very healty for the past 8 years, never have any problems with his teeth or anything. About 2 months ago, Totoro became not very active and not eating much with musshy stinky poop so I took him to a vet and the first vet said there is nothing wrong with him and his teeth, just the empty stomach and ask me to feed him with critical care. He weight at that time is about 474g(in November). A week later( weigh about 430g) , totoro is not getting any better, I have to force-feed him since he is not eating on his own, took him to a different vet, she is concern about his weight, gave me some pain killer and some medicine to boost up his appetite. In early December, Totoro is still not eating on his own, we suspect it's his teeth because he reaches his paw to his mouth frequently while I feed him, grinding his teeth very loud and I see powders in his pellet tray. I switch to a different vet and the vet took some x-ray and blood test. He said Totoro's teeth are good, very minor misaligned in the back but no infection or anything. The blood result shows Totoro has anemia and he is not sure what to do but advice to spend more quality time with my chin.
As of today, Totoro weights about 390g (has been the same weight for the past 3 weeks) He is chewing but not eating hay, not eating pellets (see some powder sometiems), wood to grid his teeth, 100% depends on the critical care which I feed 3 times a day and about 15 g each time, poop no long stinks but is covered with mucus. Yesterday I noticed that his lower teeth color has turned white from the healthy orange color. Can anyone please tell me what's going on with my chin and what should I do next?
The first two vets that I took him two are familiar with small animals (recommend from the california chin website) Should I bring the x-ray and the blood test result to them and have them look at my Totoro again?
Thank you so much for reading this and please help me if you can.
