Hiya!
I have found with my two grandchildren that they are already 'bored' with Tink and they only see her two or three times aweek.
Kids soon get bored with animals, whether it be a rabbit, hamster or dog.
As long as they are not left alone with the dog, incase of any 'rough and tumble' I am sure they will be fine.
We got our Pom when my two children were 5 and 7 and it worked well with her living until 15
1/2!
