Oh wow im sooo sorry to hear this
Chicco has never been aggressive during his 8 years with me, and i have 3 grandkids that used to play with Chicco regularly they are 10 4 and 1 year old. but as Selina explained he does love to play and will give the ball to anyone who will play with him and if your not fast enough he will try to get it back from whoever has it.
When Chicco is out and has his own ball he doesn't look at anyone else just whoever is playing with him...but as Selina has said if he doesnt have his own ball then he will pinch someone else's and i know this is not acceptable.
He is the most lovable and friendly dog i have ever known...maybe too friendly for his own good.
But he would never bite anyone intentionally he hasn't an aggressive bone in his body.
I really do hope that Chicco finds a forever home soon as he is a wonderfull dog.
I feel rather sad to read he has bitten a child as he was always gentle around my grandkids

im sorry i had to speak up in his defence
