Mountains and trails

A protection dog for an outdoor Colorado life

Colorado weekends happen on trails, at the cabin or in the snow. A protection dog that can only work in the yard misses most of that life.

Our dogs have advanced obedience on and off leash. Where the rules allow it, they walk free next to you, and they return on the first call.

Questions

Protection dogs in Colorado: your questions

Can a German Shepherd live outside in a Colorado winter?

It can handle the cold, but our dogs are family dogs and live inside with you. That is where they protect you.

How many dogs can we keep in Denver?

Denver allows no more than three dogs per household. If you already have dogs, tell Rui in the consultation.

Do you deliver to the mountain towns?

Yes. From Denver to the ski towns, the trainer brings the dog to your home.

Can the dog come with us on the trail?

Yes. With advanced off leash obedience it can walk free where the rules allow it, and on a leash everywhere else.
