Thanks for the replys and help.
Teddy started to cough violently yesterday and we took him to the vet. Said he has kennel cough .
He and Buddy were given something to keep them from getting it last time we took them to the vets for their second shots.
So they got it anyway.
We got home and then Buddy started to cough so called the vet and he said to give him the same dose as Teddy is on.
We have been very careful not to take them to doggy parks and around other dogs etc before they have had all their shots so dont know where they could have got it. Can only think that they were at the vets approx 11 days ago for their 2nd shots and Teddy at the groomers a while back then both of them there again this last wed.
