It has been a month and he still has diarrehea but only at night and his stomach makes strange noises. What could be the causes for this? Bacteria or has intestine telescoped?

I would highly advise taking Sparkie back into your veterinarian for a recheck. It sounds like he is not healing as expected from the surgery. It may be that he would benefit now from a change in food or an addition of probiotic supplements. In the meantime try a bland easily digested food such as hills I/d or boneless boiled chicken breast and steamed rice. Here are some tips to help with diarrhoea at home; https://www.petcoach.co/article/6-things-you-can-do-at-home-if-your-pet-has-diarrhea/ If Sparkie refuses to eat, cannot pass feces, has vomiting, blood in his diarrhoea or seeks in pain I would take him straight to the vet.

    Hi there and thank you for your post! If he is now having chronic diarrhea post surgery, I would be suspicious that he has developed inflammatory bowel disease. I have seen this develop in several post-op cases due to the trauma to the intestines from the foreign body. Most of these cases can be managed with a different diet such as Royal Canin Ultamino and probiotics. If Sparkie is now dealing with chronic diarrhea, I would certainly try and switch the food and give it a minimum of 4 weeks to see a difference. If he is showing other symptoms such as vomiting and lethargy I would get him in sooner. If no improvement with the new diet change, I would get an abdominal ultrasound performed. I hope this helps! Please let me know if you have any other questions / concerns. I am also available via consultation.
