I really love dogs and I am sure that they are the best friends! They are different. They are small and large, shaggy and smooth-haired. The dog can be with a pedigree, or it can be a simple mongrel. But, after all, she is also a friend of a person who wants his attention and care. Here is a song about the fact that a dog is biting only from the life of a dog. So I think that they are all good, but when a person does evil, then the animal will respond to him with evil. Although it also happens that an animal suffered a lot of grief, it still believes in the kindness of a person! I wish there were no stray dogs in the world. For the state to take care of homeless animals, it created shelters. Then there will be no angry and hungry dogs!

Description of my dog
Our family has a pet - a dog. This is a boy and he is a mongrel. His name is Tobik. It is small in stature, black with white spots on the chest and one on the tip of the tail. He has a short and smooth coat. Tobik has a black nose and small, cheerful eyes. He is already 4 months old, and he knows how to give his paw and sit on command.

Dad brought Tobik home. When he was returning from work, he noticed a small whining puppy with sad eyes at our entrance. He could not pass by and decided to take it for himself. When they showed it to me and allowed me to keep it, I was very happy. Now Tobik is my little friend.

This is an active and very cheerful dog. Although at first he was very quiet and modest, but when he got used to it, we saw his mischievous nature. Tobik often chewed on our shoes, and especially on Dad's. At first, the father was patient, but then he told me to teach the little puppy not to do that. And I began to educate and train him.

Sometimes we go to a dacha where there is a river. When I walk with my four-legged friend, we often go there. As it turned out, Tobik is very fond of swimming. I throw sticks into the water, and he always brings them, and when he gets out, he begins to shake off the water and clouds of spray are flying in all directions. Tobik also has a terrible sweet tooth and in addition to sweets, which he loves to beg, he can eat a few berries from his mother's garden.

Tobik sleeps in my room by the bed. We gave him a special rug for this. But sometimes he asks to me and until my parents see me I let him sleep at my feet. I love the way he sniffs at night.
