Ahh. Gotcha.The shots don’t work, it is like the common cold in dogs. My dogs go to enough events the usually are immune. This pup got her rabies shot. Prob was exposed then because I went to a local vet that does a lot of spays fit the local rescue. Rabies vaccine prob brought her immunity down. Been giving her honey, colostrum, extra vit c, she is hacking up less stuff today. But another pup started coughing. As long as it doesn’t go into their lungs they will recover.
