I think my new dog was abused? Please help me?

awww poor little thing aww this horrible thing happens to most pets maybe she was really being abused but its not impossible to make a new friendship with the doggy all u have to do is pet her very very gently, let him know you are paying attention to him, praise him when u get home and when u leave. OH! here's a sweet trickk put yummy food on your hand and let her come to it and eat it this will be like some sort of trust bond you'll make with the dog and he will interpret it as a respect and trust from your part...dont pet the dog if he doesnt want it he will feel uncomftrable and think u are invading his personal space, dont run behind him or grab him if he doe'snt want to let him get to know u and talk in a sweet tone of voice that way he will not get stressesd and let him meet other dogs in a safe way and walk him. I HOPE MY ADVICE HELPS MAKE THE RELATIONSHIP WITH UR DOG GET A WHOLE LOT BETTER AND MAKE HIM HAPPY :)
