– I ran across a dog that was in my yard. This is a blue pit bull that someone actually left in my yard, how do I know that someone left their dog in my yard? My gate was definitley open and it was closed when I saw him and by the condition he was in I could tell that he wasn’t able to jump our fence. It really had me hurt that someone would leave their dog in someones yard like this. As you can obvious see that the dog is very skinny. Him being skinny is a cause by the owner poor plan of having a dog. Dogs are like babies it take a lot to take care of them. So if you decide to get a dog make sure your do all the research you can if you do not know anything about dogs.
