Before finally deciding to start running with your pet, it is vital to consult it with your veterinarian first. Running can cause certain impacts, and may even lead to injuries for your dog if it isn’t done properly. If your dog has certain conditions like hip dysplasia or arthritis, it can be painful for your pet. Your dog should also be in good health as well, especially in the cardiovascular aspect. It will also depend on the weight of your dog as well. If you have a pet bulldog or pug, then running can be dangerous for them. This is because they will have a hard time getting air due to their push-in (brachycephalic) noses.
