We're keeping an eye on the lump. It's about the size of a small pea. It doesn't feel like it is attached to anything-like it's under the skin and not attached to his hip bone. When he was at the vet during the heatwave he got 2 booster shots. Maybe it's an allergic reaction. Seemed smaller today so we'll see.
Thank you again for the prayers. Haggis soaks them up!
