At Bark ATL we require your dog to have updated vaccines. The three we require are Rabies, Distemper, and Bordetella. Here is a little bit more info about the three diseases.
Rabies:
Rabies is a highly fatal viral infection of the nervous system that affects all warm-blooded animal species, including humans. The virus is most often transmitted from one animal to another through bite wounds. It then travels up through nerves, the spinal cord and eventually the brain. Once in the brain, the signs of rabies occur. Once the virus reaches the brain, death usually occurs within 10 days; it can take weeks to months for the virus to reach the brain, however.
Once signs of rabies develop, there is no cure and the disease is fatal. For this reason, reducing the potential risk of rabies in our companion pets is very important. It is so important that vaccinating your pet for rabies is required by law.
Distemper:
Canine distemper is a highly contagious disease caused by canine distemper virus (CDV). It may affect the respiratory, gastrointestinal and neurologic systems in the body. It is generally transmitted through contact with mucous and watery secretions discharged from the eyes and noses of infected dogs. However, it can also be transmitted by contact with urine and other bodily fluids of infected dogs, so your dog may become infected without coming into contact with an infected dog. Air currents and inanimate objects can also carry the virus.

Distemper was a common infection in dogs many years ago, but the incidence has been significantly decreased through widespread vaccination of dogs. Canine distemper is now most commonly seen in young, unvaccinated or immune-compromised dogs. More than 50 percent of dogs that contract the disease die from it.

Bordetella:
You might think your dog has something stuck in his throat. The cough associated with kennel cough is a high-pitched, honk-like cough, sometimes followed by retching.

Kennel cough is a highly contagious inflammation of the trachea (windpipe) and bronchial tree caused by a contagious virus or bacterium. The disease is associated most often with dogs housed in a high-density population or boarding kennel. The infectious agents can be transmitted through the air or by contact with contaminated surfaces. Puppies and younger dogs are at greatest risk, but even old dogs can acquire kennel cough.

Make sure to talk to your veterinarian about these and other vaccines. A yearly heartworm test must be done for your pet to continue taking preventative and a fecal test (to test for intestinal parasites like tapeworms, roundworms, etc.) is also done yearly.
