Help Save Our Puppy Rocko!

Me and my boyfriend adopted rocko 3 months ago at the age of 3 months, he’s become the heart and soul of our family.Many people know him from angel woods in Beaconsfield, he’s a loving caring extremely friendly little man.About a month ago he was attacked and even after that he still has the personality to trust and go out and play with other dogs he hasn’t let it stop him from being amazing.Just after he was attacked we noticed a lump on his lower jaw after countless vet visits, hundreds of dollars and tons of emotional stress we have been given not yet a single answer.We where told it’s either bone cancer or calcinosis circumscripta, both being super rare for a puppy of only 6 months of age. In order to determine what exactly it is and move forward rocko requires a bone biopsy and we have completely depleted our financial resources on him already we are begging for your help.Thank you all very much and if you cannot help financial please help with prayers.
