As pets age, they become susceptible to joint related illness. Osteoarthritis in pets is the leading cause of mobility issues, followed closely by hip dysplasia. Common signs include:

  • Limping
  • Lameness
  • Altered Gait
  • Reluctance to jump, walk, or do things they once loved
  • Difficulty rising after periods of rest
  • Refusal of food and water
  • Change in attitude
  • Sensitivity to touch
  • Stiffness
  • Inability to self cleanse

Pet owners don’t have to turn to potentially harmful prescription drugs for their pets health.

When we notice the warning signs in our pets, we take them to a trusted veterinarian. In the past, they were quick to prescribe popular NSAID’s (Non-Steroidal Anti-Inflammatory Drugs). The FDA has released information concerning the use of NSAID’s for pets – including Metacam, Deramaxx, Previcox and Rimadyl – stating that they have been connected to 22,000 cases of illness in dogs. It has become evident that these anti-inflammatories can cause serious side effects and adverse reactions, which would alarm most pet parents. Long term use is not advised. Many Veterinarians now suggest Glucosamine supplements as a first course of action, advising pet owners of the benefits of Glucosamine and Chondroitin.

Is Your Beloved Pet Not As Active As Before?

Approximately 25-30% of family pets suffer from osteoarthritis. The stiffness, pain and swelling in a pet with arthritis is really no different than what you as a human being would experience. Arthritis in pets, as in humans, is a debilitating disease that greatly affects your pet’s health and well being. With the onset of arthritis, also known as Degenerative Joint Disease (DJD), a happy, playful Fido or Fluffy can quickly turn listless and pain ridden.

What’s really going on to Cause this Pain in your Pet?

The physiological changes that occur in pets are virtually identical to that of the human body. Essentially, it is the “breakdown” of the (protective) cartilage that covers or protects the ends of bones at the joint.

Primary Vs. Secondary Osteoarthritis

Since pets by nature are very active, it follows that they are constantly subjecting themselves to trauma. Where trauma is the cause of the onset of one of many osteoarthritis conditions (as opposed to hereditary conditions), the course of the disease is extremely rapid. While a human may sustain a traumatic injury that does not develop into an arthritic condition for many years, quite the opposite is true with pets. Unlike humans, most of pet arthritis develops almost immediately after trauma to their bodies. The onset can and is often within weeks of even a minor injury as opposed to years for a human. This is referred to as secondary arthritis compared to the more usual primary arthritis in humans.

They can’t discuss their Pain

Pet owners often ask if glucosamine can be used to help the cartilage in thier pet’s joints even though they do not have a diagnosis of OA from a veterinarian. Studies on both humans and animals show that taking a glucosamine supplement regularly can be beneficial to joint health in humans and their pets.

There are signs, however, that will tell you your pet is at risk.

How Do You Know?

  • Reluctance to walk, climb stairs, jump, or play
  • Limping
  • Lagging behind on walks
  • Difficulty rising from a resting position
