I discovered my Pug eating something in the garden just now, when he saw me coming he swallowed it whole just in time for me to see a tail vanishing into his mouth. I'm assuming it was a mouse or possibly a baby rat.
We haven't put any poison down but we back onto a farm so I guess they may have done. How worried do I need to be? He is up to date with all his vaccinations, fleshing, worming etc.
