Patient discussion about PET scan

Q. Can a pet allergy cause your nose to plug, give you a sore throat and a bad cough? I recently adopted a puppy. I felt fine for about a week an a half, but 2 days ago I began to sneeze a lot. My nose plugged and I had to blow almost constantly. I also came down with a sore throat and a bad cough. Is this a result of a pet allergy or did I just come down with a cold? I've been around dogs all my life and I don't ever recall reacting like this before.

A. It can happen. Go to the doctor, if you want to know for sure. See a veterinarian for tips on making your dog more hypoallergenic. There are ways to take care of a dog and not have so many allergy issues. :D Good luck.

Q. What kind of dogs are considered "low allergy" breeds? My son really wants a dog and I am allergic. Not severely but... Promised to look into getting a low allergy one. Appreciate any info including how to source free/low cost as money is tight.

A. Take in mind that there are also other criteria for choosing a dog. Some of them need special grooming and some aren't really great with kids, but you can check out these breeds and more at www. dogbreedfacts.com. As for myself, I have had several Bichon Frises, and they can be great with kids and other pets, and they are hardy and very, very intelligent!! They arent too big either! Good luck on your hunt!
