Shhhhhhhhh!! don't let my OH know but I often feed them our greens, lettice cabbage etc, so have to buy more, they sometimes get those expensive salad leaves, however, in the summer I collect dock leaves and other leaves that they love, not been out for ages, been here with the pups who were born on 17-18th December, cannot waite to get out with them and do my forraging again.....my freezer was empty last year as I got an injury so cold not go out so much as the previouse years, I collect loads of Wild Garlic and a few other herbs, then Bilberry's, Raspberry's, Brambles etc etc......looking forward to starting again!!!!! I could get some rucksacks for the dogs and they could carry the berries!!
