Alice is 6 months old and she does this too! It varies depending on the time of day though. Sometimes (usually morning) she'll only take one piece at a time and walk around the house with it until she eventually finds a place where she will eat it. And i have to put it on the ground in front of her or toss it to her for her to take it. other times of the day she'll sit next to me on the couch and just sit there and eat as long as I kepp putting 2 or 3 pieces at a time right in front of her. When I first got her a month ago, as long as I hand fed her the first couple of pieces, she would eat the rest out of the bowl, but now that's really rare. Her and other in the litter were the smallest so I guess that could be why she takes it somewhere else and I thought maybe she doesn't want the bowl since I've been putting it under her nose many times a day because I've been worried that she wasn't eating well and she finally got irritated with it lol. Idk, whatever the reason I hope she grows out of it because we have 2 other dogs that I have to keep away from her when I'm trying to get her to eat and it's time consuming lol. I'll give the flat plate idea a try, that's a good idea
It seems like Yorkies need the perfect conditions to want to eat lol and the perfect food (i finally discovered that she will eat Orijen)
