Your d-i-l sounds very childish..You do not take their food and throw it away..What does your son say in all of this? First of all, most dogs will learn to be aggressive while eating IF you tease them..I have always been able to put my hand in any of my dogs food, because I've never teased them..Even with our shepherd..If I see a piece of hair or straw or anything else, I dont even think twice, I put my hand right down in it..if she ever bit me, it would be the last time, but, teasing teaches them to be more aggressive..I wish you lived closer to me, you could stay here..
I hate knowing that you have to live like that, it just breaks my heart for you and your baby..
