We have a Shetland Sheepdog that we keep indoors. When we leave the house, we put him out, or put him in his crate.
Suppose it is 10 degrees (F) and not wet. Is this a safe temperature for several hours outside? How about 20 degrees? Zero degrees? How do you know?
We have been playing it safe, but he hates the crate, and I don't want to confine him unnecessarily.
