Could these symptoms be anything other than distemper?

If you got them from the pound, chances are extremely high that this pair have developed Kennel Cough. These places are rife with this very contageous disease. Although it hits puppies, and elderly dogs worst, most manage to get through it. The biggest danger is the risk of it going to pneumonia. Please get them to your vet asap (but do NOT take them into the waiting area because they will pass this on). Tell reception you are outside, and wait there until your vet is ready to see you.
