Me and my husband recently moved into a new apartment complex, the same day we got a new puppy "German Shepherd mix." My husband has been having mosquito look like bites all throughout his body, his back,chest, stomach, he recently just started getting them on the face also. They look like mosquito bites,hives, things like that we don't know if it could be a flea infestation, a bedbug infestation or he's just allergic to the new puppy. We've never had a puppy or dog before. He can't take the itchy anymore he's having a difficult time breathing no runny nose no red itchy eyes, just the hives and a real difficult time breathing. what could it be?
