You will find that most veterinarians and so-called animal health care practitioners say that, "A healthy pet is a happy pet." This is just not so. In fact, it is just the opposite, "A Happier animal is a healthier animal." You can also look for the best pet charity organizations via https://face4pets.org/
As a healer and what has become known as a whisperer, I have had many occasions to work on and help animals such as horses, dogs, and cats. This is very rewarding work and the payment I receive for this is the affection of the animal.
Animals are not subject to the placebo effect so when they jump up and run around pain-free after years of suffering from arthritis there is no doubt that what I did was real and effective.
Usually, animals don't complain about their problems. If it is severe enough that they are tingling or tripping or crying then the problem/pain is very severe.
This is the only time you hear from them about their problem. Therefore, regular check-ups are a good thing for your pet. As with humans, if you allow these problems to continue in the hope that they will go away, they will come together and create additional problems, making treatment more time and time-consuming.
Most problems like arthritis are easy to treat. I'm not saying that covering up a problem with drugs or surgery is a cure. In fact, these things only make matters worse because they just hide the pain and don't do anything to fix the root cause of the problem.
