Sometimes I feed the bones without having frozen them - depends if I still have any left in the freezer on the day when I go to the butchers' - usually it is breast of lamb that I have fed without freezing first.
They will keep in your fridge for a while and perhaps you could then put them in the freezer when you have a bit more room - a dog's digestive system is different to ours and they can eat meat that is at a stage in its life that we would not even comtemplate looking at never mind eating

They can also eat meat that has been frozen, defrosted and frozen again -unlike us.
When I get my chicken carcasses from the butcher he puts them in a carrier bag to await collection and then stores them in his freezer. When I get them they are one big frozen lump so I put them in cold water just long enough to be able to separate them into right amounts for a meal and then put them into my own freezer and, so far, Harley have had no adverse affects from eating them.
