I have been told much the same, and it makes sense: for delicate digestions never feed frozen stuff - it's the same with humans. Ice cold drinks on a heated system are sometimes far from a good idea.... Or take snow: quite a number of dogs have problems with eating large amounts of snow. Food at body temperature is easiest on the system.

A kong should not present a problem, as is licked out rather than just gulped down. Rhian gets that in hot weather occasionally. But even if the dog can handle it, I don't see the point of feeding frozen meat and bone. Unless it's counted a bonus that the dog needs extra energy to defrost the stuff in the stomach.....?

Dogs or Humans would have problems eating snow. Snow would lower the internal temperature. Basic survival tells us humans not to eat snow you cant get enough water from it the same goes for dogs.
I feed my two their food frozen to make them chew their food. A piece of belly pork unfrozen just gets swallowed when its frozen the dogs have to chew it. Neither of them have had a problem with feeding raw frozen in the 2 years i have been feeding this way.
After chewing I would think that the food is already defrosted before it hits their stomach.
It was great for them when they were pups and helped with teething.
I always run their food under a hot tap just to take away any frost or ice and then feed.
2 years on they have no problems eating this way.

I don't quite understand your point about the snow - snow is frozen water nothing else, and domestic dogs don't eat it for survival but just for fun. But yes, it does lower the internal temperature, just as frozen food does.

I believe you when you say your dogs can handle the frozen food - so do many sledge dogs in northen countries. But how do you know the food is defrosted while chewing - how long does it take them to dispose of half a pound of frozen food? Don't they just swallow the still more than half frozen bits they manage to bite off instead of letting them thaw quietly in their mouths? I think a dog can bite through a piece of semi frozen food and then swallow the pieces, but since I have no experience in this I'd be interested to know how much longer it takes them.

The point about the snow is that if a human or dog was trying to survive lets say where there is only frozen snow they would have to take in loads of snow to get a good intake of water and this would not be good for human or dog. Dont know about dogs eating snow for fun we don't see snow often enough for me to comment on that.

Cassie is a very greedy springer and a piece of meat if it is unfrozen was never chewed .I did start off feeding raw unfrozen but cassie made me do a rethink and a bit of research .she was just swallowing everything I put in front of her.
I would say that a good sized piece of belly pork/breast of lamb /chicken frozen prob takes her 2 or 3 mins to eat not a lot of time but unfrozen it never even hits her jaws and would just be swallowed.
I can only comment on how my two are doing eating their food this way. They have had no problems and are doing well.
We have just spent 5 days camping and I have had to feed them their food unfrozen for obv reasons. Cassie again has not chewed her food and has come back asking for more please.
I will feed unfrozen when I have to but I think that my two get more benefit and no problems when I feed their food frozen.
I want to see my two working their jaws and neck muscles when they eat and not just see it slither down their neck.

Thanks for the clarification (sorry I don't know your name), seems you have extreme food gobblers there! As I said before, all's well if the dog can handle the shock of frozen food hitting the stomach (and your 2 or 3 minutes are certainly not enough to defrost an entire meal), then it's allright, but I know of dogs who get the runs even from fridge temperature food, never mind frozen food. Now Rhian will certainly tolerate fridge temperature and might tolerate frozen stuff (she has a fairly robust stomach), but she is a good chewer and I prefer to give her her food smelling really nicely. She gets enough chewing exercise in her diet, so I haven't had to resort to extreme measures, but I can imagine it might be worrying with a dog who doesn't chew at all but just inhales the stuff! Though I'm not sure if a canide really has a need for chewing, apart from the exercise it provides....

I might try to feed the green tripe semi-frozen though next time, just to avoid the full glory of the smell at room temperature!

my name is Jill
Not going any further into this
Would just like to say to anyone out there who feeds raw and forgets to take their dogs food out of the freezer dont worry run it under a warm tap and it wont harm your dog

Thanks Jill!

Today Rhian had a slice of calfs foot for breakfast, and it did take her about half an hour to finish this, no need of frozen slow downs! Compared to the usual poultry helping that is disposed of in 3 -5 minutes, that's quite slow food! So if for any reason, you think your dog needs to strengthen his chewing muscles, that's a good option!

As for frozen food, according to the information I've collected so far, it's just hit or miss! Some dogs will handle it without any harm, and some might get quite seriously sick from it at both ends, and some will be at any stage between those extremes, so it's up to you to decide upon taking the risk. As I have the option of feeding a handful of complete food anyway at any time, or using dried meat in an emergency, I have no problem with having forgotten to defrost dog food. I agree that with healthy dogs it is probably no issue, but for sensitive dogs it might be a different outlook.
