The Yorkshire terrier and the bichon frise are both small dogs, but other than that they don't have a lot in common. When crossed together, creating a Yochon or borkie, it's difficult to predict appearance or temperament, since the two breeds differ so much. The cross is a hybrid, or "designer dog," not a purebred canine.
Beneath the frou-frou appearance -- perhaps complete with hair bow -- beats the heart of a tough little terrier. He originally was developed as a ratter in his native Britain. The Yorkie might only weigh 7 pounds in adulthood and stand between 8 and 9 inches tall at the shoulder, but he thinks he's a big guy. Yorkies have blue and tan coats, with long, silky hair.
In French, bichon frise means "curly coated lapdog," and that's as good a description as any of this charming breed. At maturity, bichon frises stand between 9 and 12 inches tall at the shoulder, weighing between 10 to 18 pounds. Bichons are white, although the breed standard permits not more than 10 percent of accent coloring in shades of buff, apricot or cream. Bred strictly as companions, these are sweet, happy and playful little dogs.
Yochons might have the silky hair of the Yorkie parent, or the tight curls of the bichon. You could have a dog with Yorkie coloring and bichon hair, or vice versa. No matter whose hair the dog inherits, expect a pet who needs regular trips to the groomer. The ears can be upright or down. One good bet: The little dog will be extremely cute.
No matter which breeds personality shines strongest, the Yochon makes a fine companion dog. The Yorkie is more independent, while the bichon wants to be with his person all the time. With luck, you'll have a pet who is friendly but not anxious when you're out for a while. While the bichon likes other dogs and enjoys cats, Yorkies might challenge other canines -- even those several times their size. The Yochon should make a good watchdog, although he can tend to yap. Neither breed is the easiest to housebreak, so you'll have to stay calm and put in some extra effort in that department.
Both breeds are prone to Legg-Calvé-Perthes disease, which results in insufficient blood supply to the hind thigh bone, so the dog becomes lame. Surgical correction is necessary. Like small dogs in general, the Yochon might have dental issues. Slipped kneecaps, hypothyroidism and eyes problems might affect the Yochon as well. If otherwise healthy, expect your Yochon to live well into his teens.
