Please browse through our frequently asked questions to find answers to any of your questions relating to our website.

Are there any risks to my dog?

The most common side effect may be mild bruising at the site of collection. Upon completion, you can take your dog home, however, strenuous exercise should be avoided for 1 to 2 days. Health issues resulting from blood donations are rare.

Do dogs have different blood types like humans?

Yes, dogs have seven different components to their blood. Dog blood typing is more complex than human blood typing. For dogs, DEA 1.1 negative blood is universal like human O blood type is universal. One in 10 dogs are universal donors, making 90% of the dogs out there positive for the 1.1 antigen. 

How do dogs become donors?

After being identified as a donor by your veterinarian, HemoSolutions or various dog clubs, rescue groups or humane organizations, a small amount of blood will be drawn from your dog. Blood tests will determine your dog's blood type and identify any blood or organ abnormalities, free-of-charge. If your dog meets all the criteria, he/she may be enrolled. You can request an appointment for a screening online.

How long does a donation take?

10 to 30 minutes.

How often can my dog safely donate blood?

Your dog can safely donate as frequently as once a month, assuming good nutrition and iron supplementation are regularly provided.
However, we only ask that our donors donate 6 times in one year. This is approximately every 6-8 weeks.

What are my responsibilities and compensations once my dog becomes a donor?


We request that our dogs donate at least 6 times a year. Most donations will be arranged on a regularly scheduled appointment basis. We may call you for voluntary emergency donations with the understanding that you are not obligated to donation beyond 6 times. Any additional donations beyond 6 times in one year are counted towards the reimbursement payment to your veterinarian.

For specific compensation or reimbursement information, please see our donor page.


What are the criteria for a dog to become a blood donor?

  • Be healthy, obedient and even tempered
  • Be between the ages of 1 and 8 years old
  • Weigh at least 50 pounds
  • Have all vaccinations up-to-date
  • Receive heartworm preventative April through October
  • Females must never have been pregnant
  • Be willing to donate at least 6 times a year

Where and when is blood collected?

Blood is collected at a local site, usually a veterinary clinic. Local sites may change occasionally to meet the needs of HemoSolutions and its donors. Upon enrolling in the program, you will be given the exact location.

Locations include two locations in Colorado Springs, Woodland Park, Pueblo and Longmont.

Why does HemoSolutions recruit donors from the community rather than using kennel dogs like other blood banks?

We feel that accepting healthy dogs who live with caring owners is a more ethical way of collecting blood. We also feel it is a way for residents to contribute to the community of pet lovers locally and around the country.
