We have a 7 mth old Belgian Malinois and we've recently (as in today) added wet food to her diet. Ever since we got her four months ago I've made a point of petting her, messing with her muzzle, paws and food while she was eating. I've had my children (ages 4 & 9) and husband do the same thing with no problems. In fact, she would often stop eating just to kiss the person giving her attention, but this was always with dry food. This morning while feeding her breakfast with the wet food added to her dry I started petting her as usual and she growled! She gave me "that look" out of the corner of her eye with hair up on end. I immediately took the food away and pretended to eat it myself. She sat quietly while I did this and I gave the food back to her. She growled again when I started petting her. We went through this routine several times until she got to the point she showed no agression, although she was wary of my presence. This is a huge concern because of my children. I don't want to take the wet food away from her, and I'm reluctant to relegate her to her crate for meals. But of course, my family's safety comes first. The kids give her treats and play with her toys all the time, she has never been agressive toward anyone in any way until now unless you count mouthing (which we're working on). If anything, she's overly friendly. This is a side of her I've never seen before and it's very unnerving. Please help, any suggestions would be greatly appreciated. Sorry this was so long.
