I have 2 female Beagles. They are 4 1/2 years old. A friend of ours brought his male over for breeding purposes. The male has a horrible, dry, harsh cough. A lot of the time to the point of him gagging. Well, now my girls are starting to cough. We have treated them with Spectra-7 and worming meds regularly. Their Spectra-7 shot was in November 2010. My husband and I have been laid off for almost 2 years now, and I really can't afford to take them to the vet. We can purchase Penicillin from TSC and inject them with it. But I am unsure how much to give them. Thank you for your time!
