Borax can be toxic to dogs if enough is ingested. It would be best to contact your vet or an ER clinic ASAP if he ate some. You can also contact the Pet Poison Helpline (there is a fee for this service) at https://www.petpoisonhelpline.com/ if you know how much he ate to see if it was a toxic amount that requires monitoring or immediate care. If you don't know the amount, seeking care in person ASAP is best.

I'm assuming that you mean borax ant poison :) Borax can be toxic to dogs at very high doses, but it has a pretty wide margin of safety - a dog would need to eat quite a bit of it to cause any serious toxicity issues. Normally, if it's a case of a dog found chewing on an ant trap, they don't ingest enough borax from this to be a problem. You may see some mild GI upset, and in some cases the plastic parts of the trap can be an obstruction risk if swallowed, but normally there are no other serious problems seen. If Cami has ingested more than the contents of a single ant trap, I would be concerned since we would need to know exactly how much she ate to know if there are any toxicity concerns. In that case, it would be safest to take her to a vet right away so that vomiting can be induced and supportive care started if necessary.
