Over the last couple of weeks my 5 year old basset has been struggling with issues all in the bottom half of her body. Last week she had dead leg but didn’t seem to be in any pain at all. One foot was just sort of, limp. I poked it and bent it she didn’t yelp or anything. By morning she was fine so i assumed she just had a sore muscle or something. I also noticed she’s been super itchy by her butt and back feet. I checked her for fleas and didn’t see anything alarming, plus would i not be getting bit myself if she had fleas? After checking her out a little i saw a lot of missing fur and raw skin just under her butt, like where her vagina starts, and at the base of her tail. We have a vet visit tomorrow because she’s due for her shots but I’m still just generally curious if this could be because the weater is changing so maybe she’s a little dry or if there’s something wrong with my baby. Any comments?
