My guinea who is nearly 7 is having trouble eating. He's had a few problems with his teeth in his later years and only approx 9 months ago he had to be sedated to have his back teeth cut/ rasped. I'm very reluctant to let him be anaesthetised to have this done again. He's eating but is struggling. He has a constant supply of dried food, fresh twice a day and hay. We've given him all sorts of chews but he never touches them. Has anyone got any suggestions as to what I can give him to wear his back teeth down? Also has anyone ever managed to have their pigs back teeth done without being sedated? Thanks
