My pit bull terrier has had..

She's itchy all over, has hair loss & rednes,s on belly,neck,legs,even head that even will bleed if she scratches enough. We've had every test known to man done-full allergy bloodwork, testing for mites, fleas, any type of parasite, changed food, food bowls,beds,blankets, shampoo- need I go on?We've literally spent thousands of dollars with no results. I'm not sorry we spent the money because at least things got ruled out but does anyone have any ideas that the vet & I haven't thought of? Or has someone experienced something similar? We're desparate, I love her but there's no way she can be happy always taking different pills or getting poked or worse being itchy & uncomfortable for the rest of her life.

How old is your dog? My male Pit Bull has so many different skin allergies but they were much worse when he was younger. The first allergy our vet told us about is a common one...food. He is extremely allergic to chicken and so we changed his food. I had to start checking the labels cause I noticed that even some of the lamb and rice formulas have a little bit of chicken-by-product in them. I even check the labels on on his treats. I can always tell when he has gotten into something he shouldn't have...he breaks out instantly! After we changed his food things got a little better but he was still very itchy. We did more tests and found out he has pollen/outside allergies. When he was young (about 10mths to 3yrs) we had to do seasonal shots. They helped a great deal with the itching and the sores and as he got older (he'll be 5 this DEC.), he seemed to grow out of his outside allergies. We don't do the shots anymore and he hasn't had a breakout in over a year.
