My diabetic dog's old blood test site is bleeding. Can I reuse it?

Unfortunately, just as in humans diabetic patients can be subject to increased risk of blood flow issues to the extremities and frequency of infection. I can't tell whether or not it will require amputation from the picture, but the swelling can be managed with some icing. I can't recommend other meds or topicals based on this image. Use a cone to prevent any possible self inflicted harm until morning. If the swelling is getting progressive worse quickly during the night, if your dog is feverish or acting like it, or if there is uncontrolled pain, seek emergency care tonight.

I have provided a link here that hopefully will help you. There are a lot of good owner tutorials/videos for owners of diabetic pets. The best spots to obtain a bit of blood for a glucometer are the paw pad and ear tips but a lot of owners have trouble and the values may not always be accurate. You do not need to check blood sugars daily as this is not very accurate. Checking a spot check blood sugar is more important if you think the value would be low, which is more concerning than a high sugar. A blood glucose curve is a better way to monitor and this is done 7 to 10 days after diagnosis and after any dose change. Some owners monitor urine dipsticks as well. If you feel like you need more help with this disease process then you could ask for a referral to a veterinary internist who specializes in managing chronic diseases like diabetes.

Thanks for using Petco Pet Education Center, formerly Petcoach! Some pets bleed a little longer after a blood draw than others. When stressed pets bleed a little more. As long as the bleeding stopped I wouldn’t be concerned. If your pet had a blood draw yesterday the bandage needs to stay off now. Kisses to your pet!

This could be a hematoma (when blood vessels burst and cause a blood-filled blister.) from being poked three times for blood. Typically these are not something to worry about and resolve on their own. Do not try to squeeze, and keep an eye on it. If it gets bigger or doesn't appear to be resolving over the next week, I'd take Oxley into the vet. I hope this helps!

Thanks for using Petco Pet Education Center, formerly Petcoach! This is not normal or expected. This is unlikely to be from the injection site. It could have been from his nails or paws which may not be easily evident. It could of course be from anywhere else. If you notice where it is coming from (like coming from the urine) or it continues to happen and you cannot find out where it is coming from, I recommend that you have Chico evaluated by a veterinarian for further assessment. They could perform a very thorough examination to look for a source of bleeding and perform any diagnostics like a urinalysis if needed. Hopefully this is nothing concerning. Good luck and have a good night!

If it is only dripping a few drops of blood and your dog does not show any other symptoms, i would not worry about it, it can happen and it can last 3-4 days max. the blood tends to gather in the empty testicular sac and this is why it tends to bleed for several days.

It's best to just leave it for now. The wound will be small, but deep, so if you try to wipe away all the blood right now, it will likely make it bleed. It's best to wait 10 days before doing that. For now, you can gently blot away the blood with a cotton ball soaked in warm water. Blot around the wound and try to avoid the center.
