My dog's surgery drain is bleeding and falling out. Is it normal?

It looks like a penrose drain was placed these drains usually stay in 3-5 days. It is normal to see a blood discharge or seriosangenous fluid like it see in the picture. I would monitor the wound for drainage. It should be decreasing each day. If at anytime the patient is lethargic or not eating/drinking I would take him back to the vet to have it checked.

That is normal drainage - that is why the "drain" is there; so that fluid does not collect under the skin to cause a swelling. If you are worried you can always take him back to your vet for a follow-up. From the photos this appears normal to me.

Some drainage after drain removal is often expected as the volume is increasing I recommend you get her rechecked at your vets office in the morning, it may be necessary to replace the drain until the wound has further healed. It is positive that the fluid is not foul smelling and pinkish-brown indicates no current, active bleeding so unless anything changes waiting for regular office hours would be appropriate

It is normal for there to be continue drainage but it should start decreasing within the next 12 to 24 hours. If it does not, or there is an odor, it becomes thick or appears anything but blood then it could indicate further issues and she needs to be taken back to the veterinarian. I would scrub the area but instead use a very moist washcloth and rubbing the area gently with a very small amount of a mild soap. If Clarabell has increasing pain, redness, swelling or seems weak/lethargic than she needs to be seen by a veterinarian as soon as possible.

A little bit of blood/tinged fluid is not uncommon but I would schedule a post surgery recheck with the operating vet as soon as possible just to be sure, especially as one end of the wound has loosened a little. An emergency visit would be recommended if any swelling develops behind the wound, it starts to gape open more than 0.5cm or if it is persistently dropping blood.

Thank you for using Petco Pet Education Center, formerly Petcoach! It can be normal to see a small amount of blood-tinged/clear fluid (what we term serosanguinous discharge) from an incision within the first 24-48 hours following a surgical procedure. This discharge will typically decrease in amount and should have resolved within 48 hours following surgery. Clinical signs that could indicate a problem with the incision (such as dehiscence or infection) or abdomen would include a swelling that was not previously noted that is painful and may be firm or fluid-filled, discharge that looks purulent (pus) or has a foul odor, extreme reddening of the incision, or if Ashleigh is exhibiting lethargy, fever, inappetance, vomiting, or diarrhea.

A small amount of straw-colored or blood-tinged fluid is common after surgery and usually isn't a concern. Just try to keep the incisions free of discharge by gently cleaning with a warm wash cloth. If the incisions look very red, puffy, and have thick discharge that has a foul odor, then an infection could be developing. If this is the case, I would recommend taking her to a veterinarian to have the incisions evaluated. I hope this helps and that Seide feels better soon!
