Bentley not digesting food

Question
I have and Old English Sheep Dog 7 years old who has started throwing up almost daily his dinner from the night before.  About 60 % is whole pieces for food.  He east Science Diet for sensitive skin.  I have another OE same age and a 7 lb Poodle and neither of them are having a problem.

Answer
Hi Judy. He needs to be taken to the vet immediately. There's a very serious reason why he's doing this & it needs to be fixed. He could be sick or have ingested something. There could be a million things causing this. Please bring him to the vet soon!
