He just will not take his worm tablet, spits it out, I've even tried crushing it in a favourite treat but no he wont eat it, hide it in cheese, no, wrap it in meat, no. George is now overdue for his tablet and the vet makes it look easy but he wont open his mouth, his little head goes back, paws up no no mummy, I'm sure there is a way, or a place to apply pressure and their mouth opens, anyone know. ????
