My dog has been eating fine but has been struggling to poop the last few weeks. Some poops are normal, while other are red/brown soft mush. Does he have an infection. Is there medicine I can give him?

Toby might have eaten something spoiled that is causing this. withhold food for 12 hours then offer him boiled boneless chicken and rice every 6 hours in small portions. if he is eating and not vomiting, continue with this diet for 2 days. After 2 days, you can put him back gradually on his normal food. If the problem remains unchanged, take him to the vet to get treatment.

    I'm sorry to hear Toby is having some GI issues. Is the did he is on a puppy specific food? If it isn't, I would recommend a puppy specific diet. I would also recommend he have a fecal screening to ensure he doesn't have any intestinal parasites contributing to his issue. Occasionally, grain free diets can be too protein dense for certain dogs to tolerate well and a switch to a different diet may be beneficial. I would feed a bland diet for the next couple of days, and then consider switching his diet long-term. If he starts vomiting regularly or acting lethargic, I would have him seen by his regular veterinarian. Good luck!
