Gwen, I think your little mates are a bit fussier than our eldest golden retriever Jewels... she is pure guts and will eat anything... our other goldens prefer to stick to real dog food... and human food
I've even caught her eating orange peel... I thought I'd throw some round the garden like you see recommended to keep dogs off gardens... didn't work as she walked all over the garden to get the peel
She likes to eat all the new shoots on the hibiscus and the flower buds if she gets the chance... just have to take my eyes off her for a minute and they are all gone. I used to blame the ducks until I caught Jewels eating them... sorry ducks.
