I had such a busy week last week. In addition to all the dr. appointments, work and baseball, my 6 year old lab, Chloe had to go to emergency vet on Friday. We have been taking the dogs swimming in the local Lakes and ponds daily for a few weeks. Chloe was never a swimmer, but I think she thought she was swimming. Lol. She would walk up to her chest with her head underwater. But, the puppy swims. So, Now Chloe swims. Took her to a pond Thursday evening. Friday morning she was panting real hard and biting on her back end. After moving all her thick fur around I found a spot that was puffy, had scabbed over but she had chewed that off and now was raw. I started cutting the fur to get a closer look, thinking maybe a tick. The raw, raised red bumps were all over. I called vet and of course they were filled up, but brought her to the emergency vet as she was panting and whinning. They originally thought some type of allergy. Then took her in the back to clean her up. I could hear her yelping. She came back and they said her anal glands were full. What??? never heard of that. They explained it...yuk! So, they think she was so uncomfortable that she started biting as far back as she could reach. They shaved a portion of her behind area, diameter about 6" of all sores. Now she is on antibiotics for infection, steroids for inflamation, and her thyroid medication. On a good note, she lost about 10 pounds since beginning her thyroid medications. 10 more pounds to go. So, that was an unexpected vet bill. Anyone hear of such a thing? I forgot to ask, but does this continue to happen? Do these glands need to be drained often? How do you know?
