1. **Collars**:
- **Flat Collar**: Ideal for well-behaved dogs. Make sure it's not too tight or too loose.
- **Martingale Collar**: Great for dogs who tend to slip out of traditional collars.
- **Prong Collar**: Should only be used under the guidance of a professional dog trainer.
2. **Harnesses**:
- **Back-Clip Harness**: Suitable for small dogs or those who don't pull much.
- **Front-Clip Harness**: Helpful for dogs who pull on the leash, as it redirects their attention towards you.
- **Dual-Clip Harness**: Offers versatility with both front and back clips.
Consider your dog's size, breed, behavior, and any specific training needs when choosing between a collar and a harness. Always ensure a proper fit to prevent discomfort or escape. Consult a professional if you're unsure.
