Hi I have a black mouth cur German Shepard mix, he’s 3 1/2. He’s got skin allergies that pop up through out the year worse in summer with the heat, I’m hoping to take him in for some skin testing but wanted to see if anyone has had something similar in Texas? He gets patches of dry skin and the hair brushes off in spots that leave some red skin but no bleeding. I assumed it was diet and changed a few things, but it seems to have gotten worse this year. The vet said it was a skin infection he had antibiotics and soap that helped for a bit but it’s come back bad . Any suggestions or tips would be Greatly appreciated.
