How big will my puppy get?


How much will my puppy weigh?

Wondering “how big will my puppy be?” The answer can be found in the Morkie’s parents – the Yorkshire Terrier Yorkie and the Maltese.

These breeds are roughly the same size – are usually between 5 and 7 pounds (2.25 kg to 3.25 kg). Some are bigger and some are smaller, but generally this is the weight range of their offspring, the Morkie, when he is an adult. According to professional breeders, Yorkies and Maltese up to 10 pounds are considered good pure breeds.

Smaller isn’t better.

Although tiny puppies are adorable, Teacups have more health problems in general and are considered a less hardy pet.

They are more sensitive to potential hazards around the house; for example, a jump from the couch can break a leg. Very small dogs often suffer from digestive problems, including chronic diarrhea. Plus, dogs under 4 pounds don’t live as long.

It looks like Mister Famous weighs about 15 pounds in this picture. Since that time (1960), Yorkies continue to be bred down in size, often to the detriment of the breed.

On the forum, there are multiple discussions about “too small yorkies” including posts that talk about the dangers of breeding any Yorkie that is 4 pounds or less as an adult. And, owners share a number of problems they have with too-small Yorkies, including health problems and cosmetic issues like poor coat and teeth.

The biggest concern is Hypoglycaemia or critically low levels of sugar in the blood.

Low blood sugar can be a temporary problem for many small breeds when they are puppies.

But when teacups are under 4 pounds when fully grown — they’re always at risk of this common yet very serious problem. Hypoglycaemia is caused because the small dog is not able to store enough energy (food) in its tiny digestive system. Any kind of stress can cause a drastic drop in blood sugar levels which can actually be fatal!

Morkie Puppy Growth Chart

How to estimate your Morkie’s adult size

  • small dogs reach their adult weight at about 10 months – which is faster than large dogs, who take a year to a year-and-a-half to grow into their adult size
  • Morkie puppies are usually around 4 ounces when they’re born
  • by the end of the first week, they usually double that birth weight
  • All toy dogs, including Morkies, Yorkies and Maltese, tend to grow quickly in the first few weeks. They generally gain about 1/2 ounce per day, or up to 4 ounces a week until week 5 or 6
  • their weight at 6 weeks, times four, is a good estimate of what their adult weight will be
