Hi ! Happy to join. English isn't my first language, so excuse my mistakes, and please answer with simple English. I bought a new female dog about two weeks ago , Today I was walking her and I noticed that her poop was weird, could you tell me what's wrong with her? I also want to know more about her, but first things first.

Thanks for using Petco Pet Education Center, formerly Petcoach! I think your English is great. It looks like Jack is having loose stools that may also have some blood in it. This can be observed with conditions such as colitis, gastroenteritis, dietary indiscretion, intestinal parasites, among many other possibilities. I recommend that you have Jack evaluated by your veterinarian for further assessment and treatment. They may choose to check for parasites and to start medications for diarrhea depending on the results. Good luck! Hoping for a speedy recovery!
