I had i my country 4 dogs of labrador race and I walked them for about 2 hours daily,they acted according to the energy that they received.It is known to avoid fights between themselves and others in general.Also my whole life has had at home variety of pets and is the behavior of the animal world.In my area agronomic work I visited farms throughout the country and the first thing I received was the welcome of the dogs that were not kind but always calmed them and I was never attacked by them. Besides that since I have reason in my home we have had dogs and cats and lately only dogs in my hose i my country,IAlso have college education.Thank you for your attention .
