Nevilles medical bill

This is to help pay for our 12 year old dog Nevils vet bill he is having kidney problems and needs an ultrasound for a further diagnosis we have just enough to pay up to that but it will leave us financially strapped if any other emergencys occur. I hate to beg for money but im gonna do it all the same. I set a goal of $1500 which will pay all current bill and mabey another 2 visits. Thanks for anything you can help with.
