Why is my dog having diarrhea after tick disease antibiotics?
Hi there, thanks for using Petco Pet Education Center, formerly Petcoach. Diarrhea is not typically a symptom of tickborne disease so this is probably unrelated. Sometimes diarrhea can be a result of antibiotics, but usually it starts earlier in the course of treatment, so the timing doesn't seem related to that either. More likely she got into something that upset her tummy.
As long as she's feeling fine, probiotics are a great idea, and you can feed a bland diet of boiled chicken with white rice for a few days. Once her stools improve, mix the rice/chicken mixture with her kibble to gradually switch her back.
If the diarrhea doesn't improve over the next few days, and certainly if she starts acting sick (decreased appetite, vomiting, lethargy, etc), then a vet visit is in order.
Hope this helps!
