Our dog, Peanut, is a 2 year old female Dachshund. We just recently took her for her first visit to a nearby dog park. We noticed that she had foam on her lips/jowls. I then realized visiting the dog park seems to cause her to create more saliva than usual.
On our next visit to the park, we paid closer attention, and sure enough, we had to wipe her mouth off a couple times. (Of course, we didn't really HAVE to, but you know what I mean.)
Is this salivating a normal physical response, or reaction, when visiting a social area, such as a leash-free dog park?
