As with any first aid treatment, always ensure your safety and the safety of your pet. If your dog is bleeding, first and foremost, stop the blood coming out!
It is not a priority at this stage to clean the wound.
This advice is not a replacement for treatment by a professional.
Cleaning the wound
If the wound is deep or bleeding profusely, do not attempt to clean it as this should be done by the vet in a clinical environment. Ideally all wounds should be seen by a vet. However, if the wound is minor and you are not planning to get it seen by a vet, then it should be carefully cleaned before it is dressed.

You may need to carefully trim your pet’s fur around the wound so that you can properly see the extent of the damage. Ideally use curved scissors to do this to avoid accidentally cutting their skin.
A wound can be cleaned using saline or clean water. For very dirty wounds you may wish to use an approved animal antiseptic although a dirty wound should always be seen and treated by a vet.
Do not use Hydrogen Peroxide as this can damage the edges of the wound and it could take longer to heal.
Find out about different types of bleeding and find out how to bandage a wound.
All bite wounds should be seen by a vet so they can properly assess the extent of the damage and your pet is likely to need antibiotics. Find out more about bite wounds.
Specific dangers from dog bites
Bites from dogs and other animals can be jagged and often get infected. This is because dog’s teeth can harbour lots of bacteria. A bite is not always immediately apparent, especially if your dog has a lot of thick fur. Therefore, if you think they may have been bitten, make sure you check them out thoroughly, as soon as possible and get veterinary advice quickly.
Hidden damage
Even if an animal bite has just punctured the skin, it is important to wash the wound really well and look out for any signs of infection. Small-looking wounds can be deceptively large as there can be considerable damage underneath the skin and fur.
Swap details
If possible, gather as much detail from the other owner as possible. Swap details with the owner of the other dog. This could help with any possible subsequent insurance claim.
Shock
If the dog loses too much blood over a short amount of time, they can go into shock. This can happen after losing as little as two teaspoons of blood per pound.
Symptoms of shock:
Initially:
- Rapid pulse
- Pale, cold and clammy
As shock develops:
- Grey-blue skin colour and blue tinge to the mucous membranes (i.e. they are cyanosed)
- Weak and dizzy
- Nausea and vomiting
- Thirst
- Shallow, rapid breathing
As the brain is struggling for oxygen:
- May become restless and possibly aggressive
- Yawning and gasping for air
- Eventually they will lose consciousness and become unresponsive
- Finally, they will stop breathing

Treating the bite
The initial treatment for an animal bite is the same as for any other wound, except it is important to wash it immediately with clean water and antibacterial soap.
The steps are as follows:
- Reassure your pet and phone the vet. All bite wounds should be seen by a vet ASAP.
- If the vet is unavailable, wash the wound thoroughly with clean water (and antibacterial soap depending on the location of the wound).
- Stop any bleeding by elevating the wound and applying pressure. Wear gloves if possible, whenever you are dealing with bleeding.
- Get to a vet as soon as you can. Bites get infected easily; they need to be cleaned thoroughly by a medical professional and vets usually prescribe antibiotics.
- If the wound looks red and becomes inflamed, hot, or angry looking, it is getting infected and they will definitely need antibiotics.
Note: Outside the UK, if a human is bitten or licked in a wound, it is really important to get medical attention very fast and have anti-rabies medication. It is also important to ensure that they are covered for tetanus. Untreated rabies has 100% mortality, having the anti-rabies injection quickly is vital.
Type of bleeding
It may be helpful to understand the type of bleeding:
Arterial Bleeding
An arterial bleed is expelled under pressure from the heart and is bright red and frothy. An animal with an arterial bleed can lose blood very fast and quickly go into shock. It is vitally important to apply pressure fast to stop the bleeding.
Venous Bleeding
Venous blood is darker than arterial blood and pours rather than spurts. It’s easier to control than arterial bleeding.
Reassure the injured animal, apply direct pressure to the wound with a clean, non-fluffy cloth. Do not use tourniquets – direct pressure will usually stop most severe bleeding.
Keep the animal warm and dry and look out for signs of shock. Phone the Vet and advise them what has happened, take the casualty to the nearest veterinary surgeon. Keep monitoring them and reassuring them.
Internal Bleeding
Internal bleeding occurs when the dog is injured inside and there is no obvious external wound. This type of bleeding is far harder to recognise and treat and it is usually diagnosed by recognising signs and symptoms.
Internal bleeding can result from a fall, a road traffic accident, a ruptured gastric ulcer, broken bone, or many other causes.
Suspected internal bleeding must always be assessed and treated by a Vet.
Symptoms of internal bleeding:
- Becoming cold
- Becoming restless
- Gums turning pale
- Having a fast heartbeat
- Shallow breathing
- Little or no urine, dark concentrated urine or blood in the urine
- Becoming lethargic and floppy
- Blood coming from any of their orifices
If you suspect internal bleeding it is vitally important that you get veterinary help fast.
Wear gloves if possible when dealing with bleeding and dispose of soiled dressings in a yellow incinerator bag, a dog poo bag or in a sanitary bin.

I think my dog may have been stuck buy a hog near his balls and when he walks it pours blood and it must have happened late last night. I’ve got him laid down and it seems like it has stopped when he’s laying down but I don’t know how much blood he is already lost. I’m here by myself so there’s no way I could load him in the truck and make him lay still while I get to the vet. I’m going to sit here with him laying down but how long will it take before the wound heals up because I’m sure it’s a major artery a couple of inches away from his balls. I was wondering if there’s some kind of packing I can poke in the hole. Going to the vet is pretty much out of the question. It looks like he has lost a lot of blood but it’s not bleeding bad right now while laying down. He’s lying here very relaxed and alert but he does seem agitated at times. His gums are still pink.
I sent a comment about my dog’s puncture wound and it doesn’t seem like it has gone through my email. It has not showed up as being sent
My emails seem to not be going through. I need to know something ASAP
Dear Gary, I am so very sorry to hear about your dog. This is a blog post operated from the UK and it is not designed for emergency help. Your messages came through in the evening and during the night. I hope your dog is okay – they really need urgent veterinary attention. Best wishes Emma

Hi. My dog has a large growth on her side. It is now bleeding after a trip to the vet. The vet said to apply warm compress on it but she is dripping blood everywhere. No vet here is open for days (I live in a rural area). How can I cover this up and protect it?
Dear Liz, I am so sorry that you and your dog are experiencing this. The best thing to do if possible is see if you can phone the vet for emergency out of hours advice.
