katie nnnnnoneyuh answered question 1/30/2008 My Dog Is Acting Strange This Morning, Mouth Open, Panting,walking Slow,wont Really Come If Called And Just Sitting Looking Miserable..any Ideas? Try calling your dogs vet. I had a situation like that with my dog a few years ago and we called the vet and they told us what was going on and what to do after we gave them the symptoms.
