<human>: Hey, /dogs! After seeing the post about Juno's admittedly awesome new coat, I became curious - at what point do coats become necessary for dogs? I know it varies from breed to breed based on fur layers/density, but is there some common guideline? 

I'm considering buying a coat for my Catahoula, but many people I know keep telling me it's silly (their reason being "but he's a dog," so I take their advice with a grain of salt anyway.) I live in New Mexico, so it doesn't get below zero or anything, but we are very active outdoors and I fully intend on taking him up the mountain once some snow falls. I also don't currently have a yard, so we go on three or four 15-30 minute walks a day.

Give me a shortened version of the text
<bot>: Booties or wax are definitely on my list of winter gear, but I am curious about your opinion on the necessity of dog coats.
