Honestly I DO believe it's a possibility… I'm allergic to dogs as well, but I've been getting shots for years and it's hasn't been a problem. I have a good friend that is OK w/long haired dogs just NOT the short haired ones. I use the furminator on my dogs once a week and then follow up w/the kong brush to remove loose hairs. I also take them to the groomers every 6-8 weeks for bathes. It seems to help keep the shedding under control… I also do NOT sleep w/my dogs in the bed w/me, but they do occasionally get on the furniture.
Do you get allergy shots? It really helps me… I was getting allergy induced migraines.
