The Poodle is a lively, sociable, outgoing and affectionate dog who is both intelligent and amusing, and makes a wonderful and fun companion. They love to be included in all family pursuits and can be good watch dogs, announcing visitors loudly!
Both the Toy and the Miniature Poodles are very clever, trainable dogs and enjoy learning new skills, games and tricks.
The resulting Yorkipoo will usually inherit these traits. So you can expect a small companion dog who will enjoy training and games, especially terrier-type tugging, ripping and possibly digging games.
The personality of a Yorkipoo seems to be more consistent when they are first crosses (F1). As a line is successively bred, they can be either bred back to one of the original breeds (and so strengthen either the terrier or the Poodle personalities) or be bred to another Yorkipoo - in which case there is less predictability in temperament (and in-breeding becomes more of a potential issue).
Responsible breeders should be prioritising behaviour as highly as health and so it is important to find a good breeder. A well-bred Yorkipoo should be outgoing and confident, not nervous, shy or aggressive.
