Concern for the granddog but all is well

[Marthe48]

My daughter texted that their little dog might have a uti and had a vet appt for her. She is a stray they adopted last summer after she turned up at their house. At the time they got her, they took her to a vet and got her checked out. The vet said she was spay and treated her for fleas. She's been a fine dog, and no trouble until she had some symptoms yesterday. My son-in-law took her to the vet at 3 p.m today. My daughter told me this evening that the dog is in heat. We didn't think of that because of the vet's assessment last summer, also been years since we've been around an unaltered dog. My son-in-law told my daughter he is never taking an animal to the vet again. (I'm kind of snickering, can just picture the scene!)
