Gallagher's Veterinary medical bill

I adopted Gallagher November 5th from the SPCA (I have volunteered there as a dog walker and fosterer for the past 2 years). He had priror medical problems and his last owner did not want to deal with them so they brought him to the shelter. I fostered Gally and fell in love with him. He is part of my family and he means everything to him. I recently lost the job because the company is closing down ( I wasnt even given notice) I managed to get another job this week but do not have nearly enough money for the vet bills. I might not even have enough to cover my rent this month. So the thing is Gallagher has been urinating blood again. Last time he was bleeding they didnt figure out what it was from but it is reacurring. He also has to be sedated tomorrow and have his anal glands looked at which may result in costs for antibiotics, or surgery. He is in a lot of pain from whatever is happening to his little rump. I have already paid 100 for him to just to get him looked at but fear for what will happen tomorrow and in the near future for himself and for me. The money would be used for medical bills only. I wont know how much tomorrow will be but they have estimated 500 in all. I know many of you dont know Gally but he is my therapy dog and my best friend. It would mean so very much to me to get some help with the costs. I would like to help everyone who donates. Thank you so much and I love you all and im sure gally who is known at the vets as the *face licker* loves you all too <3
