Poor pup. It sounds like Sakthi has a bout of colitis (inflammation of his colon). As long as he is acting normal, normal energy level, eating well and no vomiting or blood in his stool, then this is possibly just colitis. Colitis in puppies is generally caused by the pet eating something that upset their system or intestinal parasites (i.e. roundworms, hookworms, coccidia, etc). I would recommend taking puppy to your vet for a fecal test and antibiotics to start. But for now you can do a few things to help improve the stools: 1) Bland diet of boiled plain chicken or lean ground turkey and rice 2) Fiber- add 1-2 tsp of canned pumpkin (not the pie filling) to his food daily 3) Probiotic- give daily Culturelle (over the counter) or Fortiflora (found online) to help support the natural GI flora Most pets with colitis will require a short course of oral prescription antibiotics, so it is best to get Sakthi seen soon but you can start the suggestions above to improve the stools in the meantime. Best wishes with your puppy Sakthi moving forward and thanks for visiting Petco Pet Education Center, formerly Petcoach! Take care. : )
