Both crosses share a Bichon Frise parent whose standard gives no weight, only inches. The second parent decides. The Shih Tzu side brings 9 to 16 pounds and a square, short muzzle; the Cavalier side brings 13 to 18 pounds and a coat free from curl. Neither cross has a standard.
Same Bichon parent, different second half
Shichon and Cavachon are marketplace names. No registry recognises either and neither has a written standard, so everything below is read off the parent breed standards. We say which parent each figure came from, and where a figure is not from a standard at all.
| Shichon | Cavachon | |
|---|---|---|
| Parents | Bichon Frise and Shih Tzu | Bichon Frise and Cavalier |
| Standard for the cross | None | None |
| Weight in the standards | Shih Tzu 9 to 16 lb; no Bichon weight | Cavalier 13 to 18 lb; no Bichon weight |
| Height in the standards | Shih Tzu 9 to 10½ in ideal; Bichon 9½ to 11½ in preferred | Cavalier 12 to 13 in; Bichon 9½ to 11½ in preferred |
| Coat | Curling Bichon coat; Shih Tzu “dense, long, and flowing” | Curling Bichon coat; Cavalier coat “free from curl” |
| Muzzle | Shih Tzu standard asks for “square, short” | Neither parent standard describes a short muzzle |
Size: which parent carries the number
The Bichon Frise standard gives primary preference to 9½ to 11½ inches, never over 12 nor under 9, and contains no weight clause anywhere. That absence shapes the whole comparison: on the Bichon side there is no pound figure to bracket against. Any Bichon weight you see quoted comes from somewhere else. VCA puts adult Bichons at 10 to 16 pounds, and PetMD at 12 to 18 pounds and “just under 1 foot tall” — veterinary sources, quoted as written.
The Shih Tzu standard does give a weight: 9 to 16 pounds, with 9 to 10½ inches ideal and never under 8 nor over 11. So a Shichon brackets a written weight clause against a parent that has none. The Cavalier standard supplies both figures — 12 to 13 inches, 13 to 18 pounds — starting the Cavachon higher.
Both are brackets, not specifications. A puppy can land outside a range built from its parents, and nobody can read an adult weight off a photograph. Small breeds finish growing earlier than large ones, so you learn the real answer sooner than with a big dog — but afterwards, not in advance.
Coat and grooming
The Bichon standard is specific about texture: a soft undercoat under a coarser curling outer coat that springs back when patted, scissored to the natural outline. That is what the shared parent reliably contributes to either cross, and it is a standing groomer commitment rather than a bath-and-brush job.
The second parents differ. The Shih Tzu coat is “luxurious, double-coated, dense, long, and flowing”, so a Shichon crosses two double-coated dogs. Shaving a double coat for summer is the wrong instinct: the undercoat is part of how the dog regulates temperature, and brushing it out is what helps. The Cavalier standard asks for a coat “free from curl”, so any curl in a Cavachon arrives through the Bichon side alone. Some curl, some hang, and nobody can say in advance which a puppy will do. Low-shedding is a grooming description, not a health one.
Temperament, as the standards phrase it
Neither cross has a temperament clause, because neither has a standard. What exists is what each parent document says. The Shih Tzu standard describes a dog “outgoing, happy, affectionate, friendly and trusting towards all”. The Cavalier standard describes a friendly, non-aggressive dog with no tendency toward nervousness. Both describe a breed rather than the puppy in front of you. Individual dogs vary.
Living with either one in a Georgia summer
Here the muzzle stops being cosmetic. VCA names the Shih Tzu among brachycephalic, short-muzzled breeds, and signs in those breeds are often worse in hot or humid weather — which describes most of a Lawrenceville July. Dogs cool themselves mainly by panting. A Shichon may inherit that muzzle or may not, and only a veterinarian examining a particular dog can assess its airway. Neither Cavachon parent standard describes a short muzzle.
The rest is the same for both: air conditioning, shade, water, walks at either end of the day rather than the middle. Tracheal collapse is associated with toy breeds, and the practical point is a harness, not a neck collar.
Which one suits you
We will not hand you a winner. These are the questions that decide it:
- Do you want a written weight clause on both sides, or is one parent with none acceptable?
- Is a short muzzle something you can manage in Georgia heat, or would you rather keep it out of the mix?
- Would you accept a coat that might curl or might hang, and needs a groomer either way?
- Do you need to know the adult dog before you commit? A purebred with a written standard answers that better.
Coat texture is something your hands settle in seconds. For what is in the Lawrenceville showroom now, see available puppies by breed, or read our Shih Tzu mixes and Cavalier mixes pages.
Common questions
Which is bigger, a Shichon or a Cavachon?
The Cavachon starts higher at the bottom end: the Cavalier standard gives 13 to 18 pounds, the Shih Tzu standard starts at 9. Both are brackets built from parent standards, one of which has no weight clause at all.
Does either cross have a breed standard?
No. Both are marketplace names. No registry recognises either, and neither has a written standard. Every figure here traces to a parent standard, or to VCA or PetMD where a standard gives no weight.
Will a Shichon have a short muzzle?
It may. The Shih Tzu standard calls for a muzzle “square, short”, and VCA names the breed among brachycephalic ones, where signs are often worse in hot or humid weather. Only a veterinarian examining the dog can assess its airway.
