Since for many years my husband and I have only had big dogs—Labs and Irish Setters, I was dismayed to learn from our veterinarian that Chihuahuas are prone to dental problems and often need extractions. I have been doing research and learned that the dental issues can begin as early as two years for these guys. I was careful to select a pet insurance policy which includes coverage for cleaning once a year. Now my quandary is getting Carino and Pepito to allow me to brush their teeth! So far they are very resistant. Today I ordered peanut butter flavored toothpaste because they love peanut butter. We will see how that works out. I am very concerned about this because all the articles I read stressed that dental care is critical to Chihuahua longevity.
