☆Charlie☆ PLEASE HELP!!

This is Charlie! Unfortunately, he has a large abscess in his mouth in the back near a molar. After a month went by, his mom(which is my dearest friend, and has literally lost most of her hope!) was able to finally afford his medications(Three different kinds) including his visit cost. It absolutely broke her. 

It has been difficult trying to administer his medications in many different ways, including via oral syringe which has also been extremely difficult because of the abscess causing him pain in his mouth. The connection between Charlie and his mom is truly one of a kind. His loyalty to her, and protection of her and vise versa, is an unexplainable bond. Charlie is her angel - saving her from abusive ex partners, and being there for her, to not only make sure she is protected - but to show her that his loyalty is stronger than life itself! 

That is the Magic between Dog & Humans....

PLEASE HELP! (Charlie is so worthy of saving!)
