Many times health issues will be the source of behavior problems. I recommend a thorough veterinary examination, prior to analyzing and designing our plan of improvement.
The health of a dog is very important to his owner, but there will always be illnesses that cannot be controlled. For example, overbreeding can cause problems in the bones that tend to manifest in the hip and back. Blindness due to old age is another condition beyond our influence.
Nevertheless, the best way to prevent these and other illnesses is to visit the veterinarian on a regular basis. This provides a comprehensive picture of your pet's overall health. The vet should also be contacted in case of an emergency, or when the dog shows unusual symptoms.
Nutrition falls under health. As in humans, dietary allergies, or intolerance will impact overall behavior. If you have questions it is best to speak with your veterinarian. In Las Vegas one can find several specialty dog food and supplement stores that supply quality kibble, raw or semi raw foods. These stores provide dietary experienced individuals who are good resources to use when it comes to your dog's intake.
Complementary Medicine or Holistic Medicine can work alongside traditional veterinary medicine. They are not meant to replace conventional veterinary medicine but to work in harmony with it. These Holistic treatments, include diet and nutritional, chiropractic treatments, acupuncture, essential oils, massage, laser, reiki, and stem cells to name a few.
I have available to me veterinarians that provide these services. If you are in Las Vegas I would be glad to introduce you.
