Often I hear that a Papillon owner looses their beloved pet over a routine teeth cleaning (tooth scaling) during the anesthesia.
I had numerous puppy buyers in my years of Papillon breeding, who came to buy a puppy because their previous dog , even younger dogs, did not wake up from their given anesthesia.
Papillon, Phalenes and other Toy Breeds are among those who require special monitoring while under an anesthetic because their blood pressure drops too quickly or their heart function becomes impaired.
I encourage you to teach your small dog to except a toothbrush, and offer him dental chews, and rawhide bones often.
Papillon Moms getting their hair slowly back. Most of my moms get stripped post pregnancy/delivery, and they are getting puppy food along with their babes, instead of regular adult food. Puppy food has a slightly higher protein content, which is needed for hair growth.
