How Old Is Your Yorkie?
Dogs age much differently, the largest factor being their size. Therefore, the Yorkie, being a small breed dog, will have their own timetable of aging. A good point to remember is that just like humans, as time goes on medical discoveries allows the canine to live longer. Back in the 1920's a dog generally lived 7 human years. Now, the Yorkie's life span is generally 12 to 15 years and many Yorkies live even longer.
The following is an age chart, showing the age equivalent of the Yorkshire Terrier in comparison to human years.
Milestones
Age 3 to 4 weeks - At this age, the Yorkie puppy is beginning to open their eyes. They are given their first peak at the world!
Age 8 Weeks - At this age, in most countries it will be legal for a Yorkie puppy to be given to his or her new home. If training has not begun, the puppy is ready ! Also, the Yorkie puppy will should be on almost a full diet of regular puppy food and be will weaned from mama.
3 - 6 months - It is during this time frame that the Yorkie's ears will begin to stand up. As you can see, the age that a Yorkie's ears stand up varies greatly and there is usually no need to worry if your dog goes through this phase a bit later than average.
4 to 7 months - Any time during this time period, the Yorkie will begin teething.
5 months - It is not uncommon for a Yorkie to have a perfect bite and then at the age of 5 months, their bite can go off track, sometimes within just a matter of days. A good bite is crucial to properly chewing and digesting dog food. Overlapping teeth can be a perfect place for bacteria to hide and grow. Owners must be very aware of their Yorkie's bite during this age.
6 months to 1 year - It is during this time that a female Yorkie will generally enter her first heat. It is strongly recommended to have your female Yorkie spayed, if you will not be breeding her. Doing so will greatly cut down on her chances of developing ovarian and/or mammary cancer.
1 year old - This is now the age when your puppy is considered to be an adult. Puppy food can be switched over to adult dog food.
8 years to 12 years and on- The Yorkshire Terrier is now consider to be a senior dog and care must be taken to change dog food and increase veterinarian visits, among other changes.
