You may think your dog is the peace-loving sort of pet, but I can assure you that its body is designed for war!
Similar to the human, a dog’s body reacts to trauma or disease with an all-out fight!
At the onset of any injury, the “troops” are sent in: white blood cells invade the area, especially in cases of infection by foreign objects and by bacterial or viral organisms. “Weapons” are discharged in the chemical form of histamines to dilate blood vessels, causing blood flow needed to flush out damaged areas.
To further provide protection and defense, cellular fluids are leaked into the tissues, resulting in redness, warmth, swelling and acute inflammation.
When the fight is over, the healing and repair phase begins.
Here is where we encounter the formation of scar tissue. The body does this by building a scaffold of sorts in and around the injured area.
Various cells produce and release chemical messengers that communicate between other cells. In response, cells begin to manufacture “glycoproteins” which are molecules that form the support structure, similar to bricks and mortar.
Fibrous bands of collagen form with a glue-like gel matrix, as the protein molecules combine with oxygen, acids and minerals in the body.
Together they become scar tissue and provide a temporary framework to fill in the damaged spaces, bind tissues together and hold the injured area intact, while the body attempts to grow normal tissue back.
In other instances it becomes the permanent replacement to normal tissue but is always inferior to regeneration.
There are 2 interesting traits about scar tissue that impact the dog and determine what physical therapy treatment will be needed:
1. Proliferation
Scar tissue grows in various amounts per individual animal or human. Some bodies seem to grow scar tissue in overabundance, compared to others. This may be related to the particular patient’s natural immune response to trauma. For animals that grow more scar tissue than others, extra time and attention to treatment may be needed.
2. Random arrangement
Scar tissue is rather tough and inflexible. As it forms, it does not arrange itself in consistent patterns. It is laid down in mixed, random arrangements. This makes it less resistant to tension and therefore can be broken down through stretching, deep massage, pulsed ultrasound, extracorporeal shock wave therapy and laser.
In particular, stretching is the key component of scar tissue removal. If massage and other physical modalities are used, they must be followed with stretching.
If your dog has sustained an injury, scar tissue will form in varying amounts.
If the injury is at or near a joint or in a large muscle belly, the scar tissue may be “too much of a good thing “and cause impairment in function with restricted range of motion.
In these cases, your veterinarian will show you how to stretch the area or refer you to an animal-trained physical therapist or chiropractor for additional expertise in the best way to break the adhesions.
You may be concerned that this sounds painful for the animal, but with proper use of physical agents to pre-soften (such as ultrasound, laser or shock wave), skilled manual techniques, comfortable body positioning and gentle soothing assurances to the pet, it can be well tolerated.
Conversely, there are instances when scar tissue is good and better left alone!
In situations where there is instability, scar tissue can provide some protection and support. A few examples are:
1. Partial cranial cruciate ligament tear
Surgery may not be necessary or desirable, and scar tissue helps tighten the residual portion of the ligament that remains attached. Scar tissue now becomes your dog’s friend!
2. FHO surgery
When the ball of the femur is surgically removed, it is blood callous and scar tissue that fills in the void and forms a “pseudo arthrosis” or artificial soft cushion. Scar tissue is desirable in this case!
3. Medial shoulder instability
Some sporting and agility dogs may develop this condition, similar to a dislocated joint. It often requires surgery and is followed by a long healing phase where activity and motion are restricted. Stretching is absolutely contraindicated as it will break apart or tear the desired scar tissue.
Understanding the basics of scar tissue can be important when faced with an unexpected injury to your dog!
Your veterinarian and physical therapist can help you determine when scar tissue should be left alone or when treatment is needed because it’s just too much of a good thing!

This is a very good article. I've heard that coconut oil can help heal scar tissues in dogs. Thanks for sharing your tips.
ReplyDeleteNot aware of that particular benefit but coconut oil certainly is great.
DeleteCoco Butter, as well as Coconut Oil can help smooth out and heal surface scars from surgical incisions, wounds or with keloid formations on deep scars.
DeleteAh, awesome, good to know. Thank you!
DeleteMy dog has internal scarring and suggestions? He's taken steroids but of course that's just causing him discomfort with bloating and gas. Wanted a more natural remedies??
ReplyDeleteScarring where and what from? Muscles? Organs?
DeletePlease help! My dog is 8 years old and has internal scar tissue from a preexisting heartworm condition. The scar tissue is left over from the poison that they used to get rid of his heartworm. He has a permanent cough that I'm told he has to live with the rest of his life. He has recently developed bronchitis and the coughing is non-stop. He is on steroids, Theo and Opioids. Non of this is working. Is there a way any way to remove or heal his internal scar tissue?
DeleteThis type of scar tissue is tricky. Could look into regenerative therapy and see if something could be done. Could look into integrative medicine to help out overall.
DeleteMy puppy is a show dog and she broke her tail it was casted for 5 weeks and whats left is a bump around the joint of scar tissue vet says it should go away any suggestions to help it go away
ReplyDeleteMy dog had anal glands removed almost 2 months ago due to reoccurring infections. Now she has trouble defficating. The vet says this is due to scar tissue build up. Any ideas how to help her reduce the scar tissue internally?
ReplyDeleteSorry to hear your boy is having a hard time. Yes, this can be a complication of the anal gland removal. I would look into ultrasound treatment; it might help with breaking up the scar tissue.
