Physical Appearance:
* Size: They will likely be a small to medium-sized dog, typically between 10-15 pounds.
* Coat: The coat can vary widely, from the long, flowing hair of the Pekingese to the wiry, short coat of the Cairn. The texture and color may also be a mix of both parents. Common coat colors include black, white, brown, and brindle.
* Head: The head shape might be a combination of the Pekingese's flat, broad face and the Cairn's terrier-like wedge-shaped head. They could have floppy ears or a combination of floppy and erect ears.
* Body: The body shape will be a mix of the Pekingese's compact build and the Cairn's more athletic, lean frame.
* Tail: They may have a short, curled tail like a Pekingese or a more bushy, straight tail like a Cairn.
Personality:
* Temperament: Like most mixed breeds, their personality will be unpredictable. However, they are likely to inherit some of the Pekingese's gentle and loving nature combined with the Cairn Terrier's playful and independent spirit. They may be feisty and protective.
* Energy Level: Their energy levels will vary, but they are likely to be more active than a purebred Pekingese and less energetic than a purebred Cairn.
Overall:
A Pekingese Cairn mix is likely to be a unique and charming dog with its own distinct personality and appearance. Their exact look and temperament will depend on the specific genes they inherit from their parents.
Important Note: As with any mixed breed, the exact appearance and temperament of a Pekingese Cairn can be quite variable. It's impossible to predict with certainty how any individual dog will turn out.
