what does teacup dog meen like there teacup yorkies etc?

teacup yorkie… non existent…
people call them teacups because they're smaller than the average Yorkie, a.k.a. the runt of the litter..
References :

Yes, they are just really small
References :

It's just a way of describing a very small dog such as miniature yorkies
References :

It's a fake title used ONLY by bad breeders who breed low quality sickly dogs. The title is supposed to mean "smaller than average", but it actually just means "I'm a backyard breeder/puppy mill selling unhealthy dogs to idiots!"

Yorkies come in one size and one size only. No "mini", "teacup", "toy", "micro", etc.

Since it's not a legit size, those people who get suckered into buying dogs of this label often end up with enormous dogs, twice the size they are supposed to be. Bad breeders take advantage of stupid buyers who don't do their homework.

it means it is extra extra extra small when its a puppy and extra extra small when its a adult
References :

it means they will be the smallest of the breed that is possible so if you have a teacup yorkie it is smaller than a normal yorkie. teacup breeds arent kc recognised though and they normally have lots of health problems because of the in breeding that is used to create them.
References :

teacup is a description of size. a teacup yorkie will only be about 7 pounds when full grown. there are several breeds that come in the 'teacup' size. and yes it does mean they will be small when they are adults
References :

It means that they would not usually get bigger than 4-41/2 pounds
References :

"Teacup" means very small as in it will be about 3 or less pounds when they are an adult. The dog would (if you so chose to) require xs dog clothes (extra-small)
References :

it means bad breeder !

Disreputable breeders use the term "teacup" for designer dogs at highly inlfated prices, usually with a multitude of health problems and they are short lived.

Reputable breeders do not deliberately try to breed undersized dogs, especially from breeds that are already small enough.

"Teacup" is not a breed but means "undersized" - see link below for more information. #

When someone calls a dog a teacup yorkie, or teacup chihuahua, its refering to its relatively small size. But this is just what people call it, what the term teacup means is that the runts from diffenernt litters of the same breeds have bred, making the offspring smaller than usuall. "teacups" have become pretty popular today with many people seeking small house dogs. The smallest size is properly known as toy,instead of teacup, such as a toy yorkie. I hope i answered your question have a nice day

it means its an overpriced, sickly RUNT..

There's no such thing as a "teacup" its a scam label.

Teacup is a useful term as it means that the breeder can charge more for the puppies. It has no real meaning, there's no official definition of the word and it isn't recognised by any of the major dog organisations (AKC etc).

No-one can guarantee that a teacup pup will be a teacup as an adult. Even people who breed for teacups have to use full-sized b*tches to breed as it's too risky to breed a teacup: if one of the puppies was normal-sized, the large chihuahua head would make for a really difficult birth and could kill the dog, and even if all the puppies were tiny the small size of the b*tch makes her harder to take care of- smaller dogs are more prone to spontaneous abortions. That means that there's always a good chance the puppies will grow up to be normal-sized, because all of the females of the line they descended from have to be normal-sized. They may look very small as a pup, because what toy pup doesn't?

In most dog litters (and cats, and pigs etc) there will be one or two animals who are smaller than the rest because they got less food than the others in the womb- these are the runts. These are then sold as teacup dogs for more money even though they will probably grow up to be normal size. My lab was a runt, and she was half the size she was supposed to be when we got her so they'd falsified her papers to say she was a lot younger, and had put her with younger puppies. She's now normal size. They catch up.

Of course, if they are tiny for all of their lives that's not good. Teacup dogs are prone to a lot of horrible health problems- have a look at the links below to find out more. It can be hard to treat a dog that's so tiny, and they need food at short intervals because they get low blood sugar very easily. Inbreeding causes a reduction in size and vigour in all breeds, so sometimes breeders will inbreed dogs to get smaller pups, making the pups even more prone to health problems.

Basically teacup either means a misrepresented normal pup of a small breed, a runt of a small breed which will grow to a normal size, or a dwarf or inbred dog which can have serious health problems.
Toy is a legitimate term but shouldn't be used to sell dogs, as it just means those small breeds of dogs which are bred to be companions, the way terriers means those breeds which are intended to kill vermin. All yorkies, bichons frises, maltese dogs etc are toys.

Kara-lyn: all yorkies are supposed to be below 7 pounds. That's not a teacup, that's a dog which corresponds to the breed standard. A 7 pound yorkie is actually a bit bigger than what's desired.
