I have a Yorkie who is almost 4 months old (I've had her since she was 5 weeks old). She's been having two issues.

The first issue has been happening on and off, but more frequently recently. She has trouble defecting. I took her to my vet and he said she is most likely dehydrated. Her X-Rays showed that there were no issues with her colon. I have increased her water intake per the vet's instructions. Food-wise, I originally had her on Stella and Chewy's dehydrated, which I was hydrating with low sodium chicken broth for extra water intake. I was then told that the fiber content in the food was too high and could be causing this (max fiber is 4%). So, over the past week, I have been experimenting with different high quality canned foods with max fiber ranging from 1-1.5% and mixing in a teaspoon of olive oil per meal. This seems to have helped a tiny bit, but she's still having issues defecating (often, nothing comes out and she whines as she's trying to pass her stool). A couple of days ago, she squeezed out a piece of poop that was huge and the size of what a 10-15 pound dog would produce (she's a little over 3 pounds). Should I try a stool softener?

The second issue started about a week ago. She started biting her back, which left two scabs. A day or so later, she stopped biting and it appeared to get better. A couple of days ago, her back started peeling like a sunburn. As the days go by, it peels more and more and as it peels, hair falls out with it, so she's starting to go bald on the lower left side of her back.

Any ideas as to what might be causing the above? Thanks for any help.
