If only our dogs could stay puppies forever! Unfortunately, even small breed puppies grow up and become fully grown adult dogs about one year after birth. Take a journey with us to see how small and big puppies change physically, socially, and emotionally as they grow up. 

Small Breed Puppies

Dachshund

The personality of Dachshund puppies is almost as big as their oversized ears. These small puppies will eventually grow into their ears but their tiny legs won’t get much taller. Dog parents adore the long stocky look of Dachshund puppies and they lovingly call the breed “weiner dogs”.

These small breed puppies are feistier than they appear. They’re curious about their surroundings and unafraid to bark at the threat of danger – or an Amazon delivery. Dachshund puppies will look quite similar in adulthood since they’ll only be around 10 to 12 pounds fully grown. 

Yorkshire Terrier

Yorkshire Terriers, also known as Yorkies, look like tiny teddy bears when they’re young. The cuddly look never fully fades away since Yorkie puppies only grow to be around 7 pounds. Some consider Yorkies to be “eternal puppies” because they keep their youthful appearance even into old age.  

In their first year of life, Yorkie puppies tend to be sensitive and shy. Positive reinforcement and constant praise are the best ways to train this breed. These small puppies will develop more confidence with other people and dogs as they get older. 

Shih Tzu 

If you’re looking for mellow small puppies, Shih Tzus could be the right fit. These small breed puppies have historically served as lap dogs for Chinese royalty. Perhaps due to their royal roots, Shih Tzu puppies love when their pet parents spoil them with treats, toys, and belly rubs.
