switching 10-month Bichon from puppy to adult food???

Just wondering when is the appropriate time to switch a puppy from puppy food to adult food. We have a 10-month-old Bichon weighing in at 19 lbs. Is it when they are 1-year old? Soone? Please advise.

You can switch anytime after 9 months for small breeds. :) I switched around 10 months for my lhasa apso.

My friend switched at 9 months with her 2 Bichons.

Don't forget to slowly wean him off his puppy food by mixing it with his adult food, switching him directly to a new food may give him tummy upset. ;)

Oops,I forgot to mention that Tobster.
