Ok guys I got one or ya... Titus was bitten by a deef fly about a week ago, ever since then he has had 2 bumps on his head almost like a misquito bite...well these bites were not going down and were pretty much staying the same size and they have not been itching him or anything. Well yesterday out of nowhere they got bigger and the top of the bump is all red and raw looking...now they did not bite our other dog Zeke but they seem to love poor Titus. Both of them get sprayed down with Frontline once a month but it does not seem to deter these pesky deer flies. I am not sure how to treat the bumps on his head or if I need to take him to the vet, cause it doesn't seem to be bothering him in any way he is still eating and acting like his normal self??? Anyone that has delt with this have any suggestions??
