My dog has a cold. Can he get it from humans or dogs at the groomer?

Not likely but possible. Viruses are usually species specific, but some bacteria can be spread from dog to cat. The bacteria (Bordatella bronchiseptica) most often responsible for kennel cough in dogs can infect cats. Other opportunistic bacteria can also be spread.

Dogs and humans are affected by colds or upper airways diseases but they have different causal agents. It is possible that if you have heating indoors, the air can get quite dry and make you predisposed to catch colds. Try to keep the air indoors moist by using a humidifier or water pots next to the heating.

There are a few rare cases of dogs catching the flu from their humans, but generally the answer is no. I would recommend having a family member take him to his vet for a check up to see what's going on.

Dogs can get colds or allergies. I would talk to your vet about the results of the swab. You can use a humidifier to help break up secretions. If it isn't getting better in a few days or if Apollo shows additional abnormal symptoms, he should be re-examined by the vet.

Chania could be sneezing for many reasons: https://www.petcoach.co/article/sneezing-nasal-discharge-in-dogs-puppies/ At this time, there is no known transmission of cold viruses between people and pets. It could be coincidental or it could be related to indoor allergies or air quality (since both of you are sneezing). If she sneezes beyond a week or if you start to notice it's getting worse, I recommend to have her examined.

It sounds like a respiratory infection, it could be kennel cough or a similar type of infection. you should take him back to the vet in order to start him on an antibiotic course ASAP. you shouldn't be worried regarding catching an infection from him though, it is very rare for a human to catch a respiratory infection from a dog, they do not tend to get those infection from viruses/bacterias that affect humans.

Kennel cough is spread through the air and by improper hygiene. Therefore, it could be spread to a dog that has no contact with other dogs if a human in the household was touching an infected dog and didn't wash up afterward, or by the dog being housed in an area where and infected dog had been recently. The chances of transmission by human contact are much less likely than being in a kennel situation, but still possible.
