Hopefully she is just hot. We are baby sitting a cocker this week and he is panting a lot. Our house must be warmer than he is used to. Outside he is just fine, breathing normally. But please get it check out.

We had a cocker that panted at rest all the time. After several Dr. visits, tests and xrays they said she had constricked broncial tubes and put her on meds. 2 years on the meds that never helped and we finally got the right Dr. to look at her. She took her off those meds and did blood work. Then we were told she had 'cushings'. She required a whole set of tests and new meds.

So panting can be a sign of something going on. But more than likely she is just too warm.
