Q. Male dog Barney swollowed Fishhook and bait we got the hook out but he swallowed the bait no idea what it was but now he is trying to vomit
A. Yikes! Glad you got the hook out.
If your dog ate something bad, it will remove it from its system by vomiting, if that is the case, you want it to vomit it up.
Instead I would try fasting him for 24 hours. Water only. Then start him on a bland diet. Take some chicken or ground beef (unseasoned) and boil it until cooked. Use the water to make some plain white rice and only feed him this until the vomiting stops. Keep him on this for a day or so and slowly re-introduce his food over the next couple days, weaning him off the bland diet. If his condition gets worse or he stops drinking then go to a vet
