I have a puppy that was born mid- January. He is a peek-a-poo. When will he be at his full adult size. He's only about 5 pounds now, but both parents were small.
depends on the breed..large dogs they say..at around 2 years..small dogs..about a year?..i think?...maybe someone who knows for sure can help..good luck, Wendy
Really..3 or 4 years for large dogs?....huh....see..i learn something new every day on this forum...thanks, Wendy
Full height will be reached first, for a small dog about 10-12 months. As muscle development progresses, may add a little weight as they "fill out" up until 18-24 months (small dogs).
Generally 4 months seems to be the half way mark, take their weight at 4 months and double it and that will likely be the dog's adult weight!
Talk to your vet. You'll hear something different from everyone on here. You have a mixed breed dog so it depends on the bloodline and which parent s/he follows after in size.
As the others have said it is dependent on size and breed. Our Springer Spaniel is just 1 year old. he reached his adult height at about 9 months and is now developing muscle and strength to match his size. I think the big breeds can keep growing until they are about 2 and then put on muscle etc. It would seem to follow that tiny breeds will reach their adult size younger so will stop growing at a younger age.
Most small dogs will acheive their height between 9-12 mths. They can add additional muscle bulk up to 3 yrs, although most are done by 2yrs. For big dogs add about 6 mths to the timetable
Is there a particular reason you want to know? Is it for feeding purposes? Usually a small dog will be done growing by age 1, but will continue to mature ( fill out, etc. ) till age 2+. You can feed puppy food till about 7-8 mo. or a year if you want to be good about it.
