Both of my 4 yr old GSD's had colds and spent the last month going to the vet, being put on antibiotics, and getting penicillin shots to reduce the fever. Finally they were recovering and the dry cough went away. Now a week later, my male is sneezing today sort of violently. When I lift his lips to look at his gums, he pulls away and sneezes several times holding his head tilted and closing one eye. I am wondering if this sneezing is related to his cold (he sneezed a little while he had his cold). I will be taking him to the vet tomorrow if this continues, but hoped someone has some advice in the meantime. There is no nasal or eye discharge.
