The most important part is fitting your ferret for the correct sized halter. Most ferrets will do well with the H-style harness: www.amazon.com/Lupine-Cherry-Blossom-H-Style-Harness/dp/B0006N9FWU It should be snug enough to only slip the tip of your finger between the neck and collar part. Around the belly, behind the front legs should be just snug enough to slip your pinkie finger between the body and harness. Start by putting your ferret's new harness on for maybe two to three minutes. It doesn't matter how snug it is at this point. Just be certain that as soon as it is on, to give him a treat. Remove the harness. Slowly work up the times, and the snugness, being sure to treat your ferret every time it goes on. Once your ferret is comfortable enough with the harness not to try removing it, attach the lead. Slowly walk backwards away from your fuzz, slightly tugging the lead, while coaxing or luring him to follow you. As you both work up confidence in this, you can start to venture outside with him. One important point- try not to allow him to back up quickly while in the harness. This is how most will slip them easier. And always be aware of where they are, and what they are doing, as even ferrets who have never gotten loose can some day slip the halter with no warning.
