Ok so this has been going on a while. I think it's been a gradual change, I'm not really sure. Summer is 8 1/2, but very active and overall very fit. Everything is good except that she is grunting and snoring and snorting a lot more than she used to. I think it's been this past year that I've noticed it. Kind of always brushed it off as reverse sneezing related- the snorting happens more when she's excited. But the snoring is definitely new. Then again, Nikki snored when she got old too. Most the time she breathes fine. Just excited- snort, asleep- snore. Vet has seen her and I've brought it up before. He thinks she looks fantastic for a dog of her age. He's never found anything at all to be concerned about.
