Leather dog harnesses can be stiff when new, but with a little care, you can soften them up so they're more comfortable for your dog to wear. Here are a few tips:
1. Use a leather conditioner. Leather conditioner will help to nourish and soften the leather, making it more flexible. Apply the conditioner to the harness with a clean cloth, and rub it in well. Be sure to follow the directions on the product label.
2. Saddle soap. Gently wash the clean wet harness with a soft cloth and some mild saddle soap (this will help condition and clean it at the same time) and leave it out to dry.
3. Beeswax. Beeswax is a great way to soften leather naturally and also gives it a nice luster. Rub the beeswax into the harness with a soft cloth, and then buff it until the leather is shiny and soft.
4. Olive oil. Olive oil is another natural way to soften leather. Apply a small amount of olive oil to the harness with a soft cloth, and rub it in well. Be sure to wipe off any excess oil, as too much can make the harness greasy.
5. Petroleum jelly. Petroleum jelly can also be used to soften leather, but it can be a bit messy. Apply a small amount of petroleum jelly to the harness with a soft cloth, and rub it in well. Be sure to wipe off any excess petroleum jelly, as too much can make the harness greasy.
6. Let the harness air dry. Once you've applied the conditioner, beeswax, olive oil, or petroleum jelly, let the harness air dry completely. This will help the treatment to soak into the leather and make it softer.
By following these tips, you can soften a leather dog harness so it's more comfortable for your dog to wear.
