I found a lump on my oldest boys foot very recently

It turned out to be a tumor , luckily enough it was non aggressive .
My advice to antone that finds a lump on there dog is to get them down the vets asap .
Larson has had to have his digit removed and goes in for his first redressing tomorrow . He has been great and doing really well .
Im not saying this to scare you but the only real way to know what sort of lump it might be is to get them down the vets .
Hope everything goes well for him .
