My dog is 15 months and not had her first season yet. She's not been herself for a week now - a bit lethargic and moping. She does have bursts of energy and playfulness and will go for a walk (not quite as far as normal) but is sleeping a lot more at home. I don't think it's the heat - hasn't been very warm here the last few days.
She's been at the vet for something else and he detected a very slight temperature rise...she is just finishing a course of antibiotics for a sore paw.
No sign of bleeding or anything yet but could it be on its way or is there something else I should be worrying about?!
