Yes. Distemper is a highly contagious viral infection that can affect dogs of all ages, but it is most common in puppies and young dogs. The virus is spread through contact with the respiratory secretions of an infected animal, such as saliva, mucus, or urine. This means that a puppy with distemper can easily transmit the virus to an adult dog if they come into contact with each other.
Distemper is a serious disease and can be fatal if not treated promptly. Symptoms of distemper include fever, lethargy, loss of appetite, vomiting, diarrhea, and respiratory problems. If you suspect that your dog has distemper, it is important to take them to the vet immediately.
