Definitely "NO" to grapes and raisins. Not that I have access to avacados (so I don't worry about it), but in talking about this on other lists, some of them have said that their dogs go out and eat them OFF THE TREE (!), and never had any problems.
Belle's first time with a strawberry was hilariou! She sort of took it gingerly in her mouth with the pointed end out, looked up at me and rolled her eyes, took it into the DR and dropped it (where Lu snapped it up). '
'Tis funny, they seem to have a dual coaching role. Tonight we tried broccoli and cauliflower.THIS time, BELLE snapped it up. The broccoli, Lu would pick up, hold it for a momoent, (evidently) decide it was too "hairy", drop it, and do it all over again. When she got too close to Belle, SHE grabbed it. Same thing with cauliflower:it's like LU trusted me TOD with the fruit and BELLE trusted me tonight with the vegetables! (I did find out that Lu liked the veggies a LOT better with chip dip!)
