Dermatologist Visit Update: Sergeant had his skin testing done yesterday. As I expected he has allergies to environmental elements. Dust was a major one (for me too) and I have never seen as much dust as we have in Utah. I'm from Florida and my house couldn't get as dusty in 6 mos as it does here in 2-3 days :-( There is also a mite that gets into your dog food so I will be looking for a dog food that is resealable like the RX Royal Canin was. There is nothing we can do about the grasses, weeds and trees so we will be doing the desensitization. Our serum should be here next week and it starts with weekly injections and then goes to every other week for 6 months and then we see and may need to extend his treatment for another 6 months. I will be giving the injections myself. The cost of the desensitization serum was about $250 and lasts for 6 months so it's really not all that expensive. The testing was a little more expensive than the first diagnostic visit and all together we'll have about $1300 wrapped up into the diagnosis and treatment. I figure I would have spent $1300 easily over his lifetime spot treating him. Poor baby has 2 shaved spots on his leg for the catheter and a big shaved square on his side with lots of welts :-( That was the worst part of the whole thing for me but I am hopeful all this will work and we can move on. I'll update so people will know if it's worth the investment. :yes:
