Collecting a blood sample from your pet can be a scary experience as you understandably don't want to cause your four-legged friend any discomfort. You should speak to your veterinarian before you take any samples and share any concerns that you may have. They will be able to talk you through the process and show you how to take a sample, quickly and without causing any stress or discomfort to your dog. The best places to take samples are usually inside the ear and the pisiform pad (the pad at the back which dogs do not walk on). Older dogs may have hairless calluses on their elbows - this is the perfect spot to take samples as it's practically painless!
