Help max get his treatment

hi and thank you for reading.

3 years ago we took in a puppy that our horrible neighbour left outside in a box when she left the day before.

so cute and small we named him Max!

since then max has become a loving dog and comfy pillow to our little boy.

but recently max hasnt been himself, he has no energy and not interested in his favourite doggy biscuits. This is because we have just found out max has a tumour growing inside his neck and it gets bigger all the time.

Our vet is willing to help us but at a cost of £635 which is more than we can afford

This is when i became searching for help and stumbled across this site.

PLEASE PLEASE help us, we dont want to lose Max!

thank you in advance for anything you can give.
