Why are my Golden Retriever’s teeth yellow?

Yellow teeth in a Golden Retriever can be caused by: 1) long-term eating of red meat like beef or lamb, or high-sugar, high-fat foods, leaving pigment deposits; 2) poor oral hygiene causing plaque and tartar that yellow the teeth.

3) As the dog ages into its senior years, teeth may yellow naturally as part of aging; 4) vitamin deficiency or dental disease can also yellow the teeth.
