My momma s best friend TJ

Hello this is Kara and I decide to set this fund for my special sweet momma who loves her dog ( mixed Great Dane and shepherd and weight about 100 pounds )  his name is TJ and he is my momma best friend.
few years ago my momma diagnosis PTSD and TJ is always on her side which makes me feel better about it because my momma has 4 kids and all are grown up and have own family so my mom lives alone with TJ  and he is everything to her. Tj have one HUGE mass which you can see in the picture and my mom is broken because she could not afford to get it out and it keep grow bigger and bigger every year and my mom took him to the vet yesterday and ask if it's safe to have it removed because of his age and yes they said they can do it but unfortunately my mom doesn't have the money and she is on disability because of PTSD now I am asking all of you deep in my heart to help raise for her or share around and get what TJ need that will make my momma happy! If you guys know my momma she loves TJ deeply and she loves to help people now it comes to her that she needs help please share around. 
Thank you from deep in my heart :)
