We generally recommend feeding defrosted product, but there are exceptions.
It's ok to feed frozen cubes, but you need to be sure that your dog is good at taking their time and chewing. Don’t feed frozen cubes to a ‘gulper’ as they may try to swallow it whole.
Tripe is pretty smelly - some people really struggle to deal with defrosted tripe. In this case, you may wish to feed it frozen, but you need to be sure that your dog is good at taking their time and chewing. In the heat of the summer, food will defrost quickly outside. Again, if your dog is not a ‘gulper’ you may wish to put some frozen food outside and let your dog treat it like a meaty-ice-block.
Some dogs have not had much practice at chewing meaty bones and they will try to ingest them too quickly. Feeding frozen meaty bones can slow a dog down, giving them a chance to get used to using their jaw muscles properly.
We usually find cats prefer their minced products to be defrosted.
