Research shows that Yes , pets do help us live longer , healthier lives . Reducing loneliness , depression , blood pressure , heart rate , cholesterol levels and heart disease . They also provide us with companionship , unconditional love , and in some cases a feeling of safety . It has been written that our pets increase and improve our quality of life emotionally , spiritually and phychologically . I have a friend who uses her miniature horses to visit nursing homes , it is amazing to see watch the interaction between the horses and the residents , there is an immediate difference in them . I work with mentally and physically challenged children with horses , with the same results , they come alive . Personally having horses , dogs , goats and cats I am a firm believer that pets are one of the best preventive medicine's available in the world . Not to mention they are also some of the best psychologist in the world . I have found that I actually like and trust animals more than some people I have come across . It is hard to beat the love of our pets and the love of a good man . I am blessed and thankful for both .
