Yeah our current dog has barely ever been to the dog park, we decided to change it up and bring her there. A day or two later and she has kennel cough. But I also think our dog has a bad immune system. We pet sit a dog for 5-6 hours and it had a bit of a sneeze. We all just thought it was allergies because it was a young dog and the vet assumed it was allergies. Well a day or two later again and our dog has a sneeze, tons of green snot, and our vet suspected it was a bad infection, possibly pneumonia. She is only just about 2 years old and already seems to be getting any disease she gets near.
