Please help Kona

On August 30 at 8 pm an aggressive St.Bernard- just by the path and field at the south Courtice Dog park attempted to attack my girls ( 14 and 11) my senior 10 year old Golden (who has a football size tumour on his belly) jumped in between this dog and my kids.  

I understand having a dog comes with expenses but emergency vetcare is expensive. If you could spare any amount to help us pay for Kona’s assessment and surgery we would be incredibly grateful. 
Thank you in advance for any help you can provide to us. We would be forever grateful and would certainly pay it forward. 

Thank you
