Can't decide if I should take her in or not. If we go out walking for a while, but really not that long, lately when Mia pants she is sounding congested. It sounds upper respiratory to me. She's also tiring a bit faster than usual in the heat. It wasn't too hot tonight- low 90s and after about 30 minutes I'm pretty sure my vet thinks I'm a hypochondriac though. This has been going on a couple weeks. I'm wondering if it could be an allergy. It is very reminiscent of when I took Summer in for similar noises and it turned out she had a mild allergy to something environmental. Indoors though her endurance seems same as ever. She'll chase the ball all day if I let her. So maybe it could be temperature?
