Rescue pup medical,food, blankets and toys

I rescued this poor puppy he is a pibull . The puppy is so so thin when we went to get him he was alone in a garage with no bed no blankets no food no water. When the guy handed opend the garage where the puppy was all alone the guy pushed the puppy hard with the broom. On pictures the guy send me you can see the grip he put around the poor baby's neck. He does not even know how to use a water or food bowl its so sad. I could not leave him their he could not stand up his back legs gave in i gave him food and he did not know how to eat it i had to feed him with my hand. He just wants love and you can just sit next to him and he will get on your lap he is still very very scared and just bones he is getting cold all the time. When i got him yesterday i gave him a bath their was ticks all over his body i took off with my hand when i thought everything was done theu made nests in his ears full of them i didnt have alot of mony went to vet they gave me revelation and antibiotics. I need to get him food that will make this poor baby fat he is so thin and shakes of the cold. He still needs to go for scanes to see his bones is not broken, injections he does not know how to play with toys he only bite the teddy once would like to get him different toys and see how he does i hope to get him all better by Christmas. I named him Samson witch means strength from god because he survived thank you all for the help if you want any pictures and videoas of how he is doing please contact me on 0744152922
