Lots of hugs for you Kerri. Your pups appreciate all you do for them. I'm sure you can get Gus's tummy troubles straightened out, the paw issue sounds like it's a foreign object and the lump could be anything until you hear otherwise. I know how overwhelming emotionally (and financially) it is to have health issues with more than one dog at once, but you will get through all this. Deep breath, and one step forward at a time. Sending lots of positive get well thoughts to your three pups.
