Help with upcoming leg repair for Rocky

My male dog Rocky got his lower fang tooth broke from a fight with his female friend. When taken to vet she noticed that Rocky's teeth need an extreme cleaning and that it could be more than one tooth. Money is also needed for blood work because he continually licks his paws and vet said that's usually a sign that he's allergic to something and blood work is needed. The total vet bill is $975 but $600 has been raised so far most by Peaceloveandpaws in Detroit! Vet wanted me to come with at least $750. PLEASE HELP!!
