It is often said that the decision to buy or take in a dog involves a lot of responsibility and a number of duties. Nevertheless, having a four-legged friend has many advantages as well. Thanks to regular walks, we provide outdoor movement not only to the pet, but also to ourselves. Stroking a dog and playing with him reduces tension and stress, as well as makes you smile. The animal will also be a great companion for the elderly and lonely, who lack company on daily basis.
