How Low-Level Laser Therapy Can Improve Your Dog’s Health

Low-level laser therapy or cold laser therapy is a non-invasive therapy that relieves your dog from pain and inflammation. Laser therapy promotes healing in body tissue, ear gums, skin, and muscles. Light is used in it to stimulate cell regeneration and enhance blood circulation. Pain is decreased by reducing inflammation through the opening of blood vessels.                                                                                                            

It is usually known by different names like Photobiomodulation (PBMT), low-level laser therapy, red light therapy, and cold laser therapy.

What is Photo-biomodulation or cold laser therapy?

Laser therapy is a photochemical process in which biochemical reactions occur by the interaction of light with body cells. These reactions help enhance circulation at a cellular level, increase collagen production, stimulate the immune system, and develop muscle tissues.

How does laser therapy differ from surgical lasers?

The surgical lasers penetrate much deeper into tissues with higher frequencies, but in the case of laser therapies, there is no need to cut in your fur baby. Veterinarians used laser beams with low frequency over the skin surface and fur to treat infected tissues. There is no need to shave them either.

Benefits of laser therapy:

Laser therapy for dogs at home can help you with:

  • Traumatic wound healing 
  • Surgical wound healing 
  • Immunoregulation
  • Improve the metabolism of specific tissues
  • Speeding the healing of infection 

Conditions treated by laser therapy

  • Osteoarthritis and joint pain
  • Acute and chronic infection
  • Spinal disc swelling 
  • Post-surgical nerve tissue repair 
  • Post-surgical and soft tissue trauma 

Amazing, isn’t it, but wonders do not stop here. Sometimes the therapeutic laser is used when a dog gets an ear infection and looks swollen and inflamed. It is also used for broken toes and legs. It can treat chronic and acute injuries and back disc problems. It helps to block pain. 


Usually, musculoskeletal problems come with age in older dogs, with much pain and discomfort. They show the following signs:

  • Restlessness 
  • Abnormal sitting 
  • Lack of appetite 
  • Trembling 

How much time is required for each laser session?

Each treatment unit varies in length depending on power density but is usually one minute per site, but most sites require 3 to 8 minutes. Lasers are classified into four classes. In veterinary medicine, class 3 and class 4 are commonly used. High power laser requires a shorter time to provide the necessary energy dose into the tissues of animals. The frequency of therapy treatments depends on which type of laser is used and which problem is treated, whether acute or chronic.

Laser therapy has significant uses for arthritis. If your dog has arthritis and hip dysplasia, you should go for low-level laser therapy with two to three sessions per week. Lessen the session to once a week once you see the improvement.

How does laser therapy work?

Light energy is used in therapeutic lasers with specific frequencies, and this light causes change at the cellular level in a dog’s body.

How does laser therapy use with other medical treatments?

In a multimodal pain management program, laser therapy has a significant role. It can be coupled with chiropractic care, physiotherapy, acupuncture, hydrotherapy, and medication supplements. 

Involved Risks:

There are a few problems where laser therapy is not recommended. In the case of cancer, if it has metastasized (spreading to other portions of the body), laser therapy cannot be used because it could accelerate the tumor growth. Laser therapy should not be applied over the uterus of a pregnant female dog.

The laser will be safe if it is so weak. Some effective therapy can cause the burning of tissues and damaging retinas if misused. Retinal damage is the most significant danger when any person directly looks at the laser beam. You must provide safety goggles for your dog’s eyes and yours. 

The bottom line is that it does not matter the reason for pain and where it occurs in the body; laser therapy is a contribution.
