We have a 6-yr old neutered 4-lb Chi named Peanut who is our child. He goes everywhere with us...we even got him service certified so that he can travel and stay anywhere we go. Two weeks ago, Peanut started having diarrhea. Took him to the vet where they did blood work and fecal sample (couldn't get much). Blood work showed low protein and other and liver count off. Vet was hoping the diarrhea was causing liver count to be off. Started on meds and said if it got worse to come back. Next day he literally had an explosion of liquid so took him immediately back and took pad and sample for them to check as previous stool sample showed nothing. Stool still showed nothing and vet not sure..not dehydrated but gave him charcoal to counter any possible toxins in system. Next day...had a wonderful solid (black of course) stool. However, he started screaming every time we picked him up like he was in pain. We were afraid he was hurt when they gave him the charcoal, so afraid to take him back and subject to more pain. Have been limiting his movements and giving meds. Diarrhea still watery and he has foul gas and diarrhea has strong odor. He is eating and drinking...giving him homemade boiled rice and chicken only. Have tried the pumpkin to see if it helped which it didn't. Does anyone have any ideas or maybe seen this? We are devastated about this and don't know what to do. We were hopeful that Chihuahua breeders that know this breed better than vets might have some ideas or suggestions. Thanking you in advance for any help for our Peanut.
