The thing is since Yorkies are small breed dogs, even the slightest weight loss can change their appearance. 

Overfed Yorkies can easily gain weight, which is also reflected in their appearance. Your Yorkie’s diet directly affects his lifestyle. 

Yorkies that are overweight tend to run and exercise less, while Yorkies without weight issues tend to be more energetic.

In general, Yorkies are very energetic animals. Their high energy continues into adulthood. It is a common belief that Yorkies have a temperament similar to their owners, and will adapt to your lifestyle.

It’s all about how you treat your Yorkie. While some Yorkies are very well-behaved and calm in their transition to adulthood, some still maintain their childhood habits.

For example, a poorly trained adult Yorkie will tear apart anything that comes into their paws if you leave them alone at home, while a well-trained Yorkie will not do this type of damage to your home.

Yorkies live for an average of 12-14 years. A Yorkie enters maturity at the age of 8 and old age from the age of 10.

Yorkies who are considered to be old should be fed with dog foods that are specially prepared for older dogs and contain multivitamins and low fat. Exercise needs should be met regularly and they should be made as comfortable as possible.

Do Older Yorkies Experience Psychological Changes?

There may be some psychological changes in Yorkies transitioning from senior to old age. Some Yorkies may experience some anxiety issues during this transition period. 

A lower mood and decline in engagement have been observed in some Yorkies as they get very old. Yorkies are very sensitive and emotional animals and like any animal, they will feel the transition into old age. 

During this period, you should treat your Yorkie, who is more sensitive than ever, as lovingly as you can and make him comfortable. Your Yorkie still loves you and plans to be your faithful companion until the very end.
