Blood transfusion can save a pet’s life — but that may not occur when there’s a blood shortage.

That’s what’s happening now as veterinary hospitals across the country are asking for blood donations. Dog and cat blood is often ordered from blood banks, but with the current shortage, clinics are depending on local feline and canine donors instead.

Donor requirements may vary a bit among clinics, but they generally follow similar guidelines. Pets should usually be 1 to 8 years old and spayed or neutered. They also need to be current on vaccinations and free from any medications. As for size, most veterinary hospitals look for cats over 10 pounds and dogs under 50 pounds.

Blood donation only takes about 15 minutes. If you can see your cat or dog being a blood buddy, contact your veterinarian for more information on how you can help.
