You know what I have learned in my 4 years of owning a Yorkie- ( in my experience with MY dog) All those chew things do is cause issues! Peanut has had issues with Bully sticks, and Texas Toothpicks to Himalayan chews! My vet told me sometimes (not sure about the Himalayan chews) bacteria gets on those sticks and that is what causes tummy issues! I will not give Peanut any type of chew anything anymore- It is really not worth the Vet bills! He also doesn’t miss them, the minute I pulled at the Texas Toothpicks and Bully Sticks is the minute he forgot about them and moved on to something else!!
That is just my take on it-
Hope Izzy feels better!!
