Dogs that fail training for government work typically have some explosives detection training. The dogs are highly active and in most cases, will require a lot of attention, additional training and significant exercise. They are crate-trained, but not house-trained. Most dogs have not been exposed to small children or animals other than dogs.
It could take up to 90 days for a dog to adjust to your home, family and other pets. You may have to seek professional assistance if your dog is not able to adjust.
