Ok, this is kind of a weird question, but I think my 6 mo. old is in heat, there's blood...my question is, I am dying for her to get to play with my mom's puppy (5 mo. old maltese) they are bff's, if her giardia test comes back clear today. But now that she is in heat, I don't know if she can. But I mean, he's all of 5 pounds, and is only 5 months old. I mean, is there anything to worry about there??
