I've got a new 4 year old bitch who shows her tongue allot.
Often even before i can open the door to walk her or when i just pet her inside.
It looks the kind of panting a dog would do in the car or at the vet when its nervous.
Would it be just some kind of over excitement or nervousness/stress, or could there be an underlying health problem?
It doesn't look like she tired, there is no reason to be so either.

Wonder if anyone here got dogs like this and if would be good to get her checked at the vet.
