We just adopted a four month old rescue pup and have started crate training. All of my other sibes have been adopted as adults, so this is new to me. Our new one sure can be vocal, but I think it is a great idea to have any dog be comfortable in a crate. Had not thought of it as fire prep, but should have since we are in socal.
Our huskies seem to have sensitivities to poultry and grains. They get gassy and have upset tummies. Probiotics really do work great: https://www.askariel.com/pet-probiotics-p/81.htm I haven't heard of using apple cider vinegar for heartburn, we have used it for fly control
