Generally, the biggest issue that we may see with ingestion of borax is stomach upset and vomiting - so it's very possible that you may see this. In large amounts, borax can cause kidney failure in dogs, but this is uncommon and usually the result of long-term exposures rather than a single ingestion. If you're concerned, you can always opt to take Rocky to your nearest emergency vet for supportive care to help prevent any problems.
