The past three nights my dog has been throwing up his dinner. I have changed his food from those meat rolls from the supermarkets to dog mince and chicken necks. I don't think this is whats doing it, i think it is because he doesn't chew the chicken neck. I went to clean up his spew from the patio floor and there was the whole chicken neck intact!!! I'd love to continue giving him chicken necks but not if he keeps doing this, would chicken wings be better? or should i give it a miss altogether and just give him those greenies bones? he chews them. After he threw up tonight i just gave him more dry food, incase he was still hungry from throwing up his food, and he ate them all up straight away.
