For real? 1 year. In dog years? Well, only dogs know that for sure. I assume you mean from birth.
The dogs have to be 12 months to have puppies...
i would recommend about 10 months to a year old. it depends on their size and maturity also!
from 6 weeks through 1 year and 2 months of age
A 55-year-old is approximately 660 months old. This is calculated by multiplying 55 (years) by 12 (months in a year).
Gosselin's dogs are 16 months old.
5 to 6 months
If you bring the puppies in to your vet office, they will tell you when shots are needed.
6-8 months old
9 years x 12 months in a year = 108 months
A 4-year-old is 48 months old, as there are 12 months in a year. To calculate this, you simply multiply 4 years by 12 months per year (4 x 12 = 48).
For small breeds, female puppies can come into heat at 5-6months, and, if bred, can have a litter at 7-8months. Most breeds over 35lbs at adult weight do not come into heat till 7-9months, some later. However, do not allow puppies to breed this young. Sibling puppies WILL mate as soon as they have a chance.
A 6-year-old is 72 months old, as one year consists of 12 months. To find the total months, you multiply 6 years by 12 months per year (6 x 12 = 72).
