Bob Martins worming powder

[deste]

Anyone else's dog violently sick after eating them. He was sick the first time but I thought it could have been anything that caused it. I gave him half a sachet this time but he has been sick again. What do you give your dogs to worm them or do you take them to the vet?

Never tried these, but have heard they're not as effective as those bought from the vet.

Same thing with flea treatments. So personally the vet every time for me.
