I made these treats recently for my dog during a four-day heatwave that broke a forty-year temperature record and almost brought the UK to a standstill. We do emergencies terribly well in the UK, not so much extremes of weather!
You just need :
500g pot of plain yoghurt (I used Total 0% fat because that’s what I always buy)
200g blueberries (about a cup)
Pop everything into a blender and blitz, or pop into a batter jug and blitz with a stick blender. Pour into silicone cupcake cases and pop into the freezer. Once the ‘cupcakes’ have frozen they can be tipped into a freezer bag for easier storage.
This works very well poured into a Kong, just make sure to wrap it in cling film first (leaving the top open of course!).
