CHD is most commonly associated with dogs, and is not uncommon in many dog breeds, particularly the larger breeds.CHD is abnormal formation of the hip joint. The head of the femur is supposed to match the socket of the joint. The lack a snug fit between the ball and socket of the hip joint are those diagnosed with varying degrees of Hip Dysplasia. Some pups may only have a slight change, while others can have complete dislocation.
The following are the primary factors leading to CHD-
Improper Nutrition – Proper nutrition is crucial during the growth phase of a pup. This does not mean that food or calories should be restricted. Ideally, a high-quality meat-based diet is essential for growing pups and by using a large or giant breed puppy food will assist you in ensuring your growing Lab pup receives all the nutrients its needs while maintaining a proper caloric intake. An overweight puppy or dog adds much unnecessary stress on the hips and joints.
High Physical Activity – Large and giant breed pups are in the growth phase of development from birth to 1 year of age. The more strenuous exercise it receives during this period, the greater chance of it developing Hip Dysplasia or arthritis later in life. Activities like climbing stairs, lot of play / running and jumping should be avoided.
Possible signs of CHD in young pups and older dogs can include –
- Runs with both back legs nearly together (rabbit run)
- Reluctant to rise after exercising
- Sits back unsteady
- Legs not parallel when standing straight
- Difficulty climbing stairs or inclines
- Look slightly undeveloped in the rear quarters
- Boniness to the pelvic area from lack of good muscle development
- Inability to extend the leg backward very far
- Decreased range of motion or stiffness
- Rock forward to support more weight on the front legs
- Tip-toeing lightly on rear legs
- Reluctant to jump or stand up on hind legs
- Sits rather than stand
- Decrease in willingness to exercise
- Popping or snapping sounds when walking
- Soreness after lying down
- Sensitivity to touch of the hindquarters
- Hind leg lameness
Prevention
When selecting a puppy, make sure the dam and the Sire did not suffer from CHD.
Picking up the problem as early as possible affords your pup the best chance of finding the right option, whether medical or surgical, to minimize the arthritic changes that will develop secondary to the Hip Dysplasia.
Treatment
Drugs - Non-steroidal anti-inflammatory drugs such as aspirin, naproxen, Adequan, and Cosequin have been proven effective in many cases. These anti-inflammatory drugs, accompanied with such treatments as weight loss and moderate exercise, will help to alleviate the pain and inflammation around the jip joint.
