The collar is made from strong nylon to stand up to wear and tear.

This collar doesn’t only offer control, it also provides comfort for your dog with padding on the nose loop and pressure being put on the back of your dog’s neck rather than their throat to prevent choking. I found that my dog could eat, drink, and pant comfortably in this collar. It comes in a wide range of size to suit all breeds.

I use this collar with my springer spaniel regularly and gives me a lot of control, as well as being comfortable for her to wear even on long hikes.

The collar gives plenty of control, allowing you to steer your dog from the nose and stop bad behaviors efficiently.

The collar also offers an optional muzzling action to allow you to control your aggressive dog safely and quickly. The Halti is comfortable for your dog, with no metal parts touching your dog’s skin, allowing for gentle corrections. When using this collar with my dog I found it gave me the control I needed to make training more positive for both me and her.

Remington Rope Dog Slip Lead review

Features

  • Best slip lead
  • Strong and durable
  • Allows for gentle correction

The Remington Rope Dog Slip Lead is a fantastic choice for gentle correction, tightening gently with a soft adjustment on your end of the lead or when your dog pulls. You can use the lead around your dog’s neck or in a figure of 8 around your dog’s nose and neck depending on the control you need. It’s even recommended by trainers for control and correction.

The lead is made from strong, braided nylon for durability which is also soft enough to offer comfort for your pup. Since this lead is adjustable, it will suit most breeds from small to large, but may be too chunky for toy breeds with delicate necks. I found that this lead was both stylish and practical, and enjoyed the option of 3 beautiful colors.

Pros

  • Many owners felt that this lead was great value and high-quality
  • Owners found the lead easy to slip over their dog’s head and felt secure in the knowledge their dog couldn’t escape on walks
  • Helps to stop pulling and other negative behaviors on walks, giving more control and allowing for easy corrections
  • Option to use around the neck or as a figure of 8 around the nose and neck for greater control
  • Durable and strong without being too heavy, with owners saying they felt it was well-made and long-lasting
  • Choice of colors, with owners saying they felt the lead was stylish and looked good on their dog

Cons

  • Some owners found that their dog coughed when the lead tightened, which they found concerning
  • Some found that their power chewer could chew through the lead when left unsupervised
  • Some stated the lead was stiff at first and therefore didn’t slide and adjust easily
  • Can be too chunky for small or toy breed dogs

  • Strong and durable
  • Provides gentle correction

The Max and Neo Dog Gear Nylon Reflective Martingale Dog Collar with Chain is a great, heavy-duty option, made from strong nylon webbing with a chain for extra strength. A lockable clasp prevents unwanted unlatching during training, while also keeping your dog safe if you need to remove the collar quickly. The collar gently tightens when you pull on the lead during corrections, or when your dog pulls.

It’s soft and wide enough to be comfortable on your dog’s neck. This collar is suitable for small to large dogs. I found the collar easy to use during training and when on walks and liked the bonus of the collar being reflective.

Pros

  • Owners stated they felt the collar was well-made and secure for their dog
  • Some stated they felt this was a gentler option than a choke chain and was comfortable for their dog

  • High-quality and well-made, with some owners saying they felt it was much better quality than other similar collars
  • Many liked the fact that the company donates a collar to a dog rescue for every collar they sell

Cons

  • Some found that the clasp didn’t stay locked, making the collar less secure
  • Some stated that the chain part of the collar turned their light-colored dog’s fur a darker color
  • Some owners felt the collar didn’t give them as much control as they would have expected
  • Materials are thick and heavy, which can make the collar too heavy and large for smaller dogs
  • Some found the sizing inaccurate, leaving them with the wrong sized collar for their dog

Things to Look For in a Collar For Aggressive Dogs

When you’re looking for the best collar for an aggressive dog, you should keep the following in mind to ensure you get the right collar for your needs:

Strength and Security

1 of the most important things is to ensure the collar you choose is strong and secure. It’s crucial an aggressive dog can’t escape from their collar during walks, as this could lead to a dangerous situation.

Look for collars made from strong, sturdy material. If the collar has a clasp or buckle, ensure its lockable or very secure and won’t come open while your dog is wearing it. Check the reviews and description for this and avoid ‘quick release’ clasps.

Control For You

It’s vital you have as much control as possible when working with an aggressive dog. Consider how the collar allows for corrections and control, and how well you feel the style of collar would fit your needs.

Some collars will allow you to lead from the nose or put pressure on the back of the dog’s neck for control. Others may tighten gently to allow for quick correction.

Comfort For Your Dog

Control and strength should not take the place of comfort for your dog. The best collars for an aggressive dog will provide comfort as well as control. Look for features like padding, soft material, and a comfortable fit.

High-Quality Materials

Choosing a collar made from high-quality materials will ensure it’s more durable and comfortable for your pup.

Correct Size For Your Dog

Choosing a collar that is the right size for your dog ensures they’re comfortable, as well as making sure they don’t escape. It’s also crucial that the collar fits properly so that your corrections are effective. Measure your dog’s neck carefully and check the size guide.

What Causes Aggression in Dogs

No dog is born aggressive, and an aggressive dog isn’t a ‘bad dog’. Aggression forms due to experiences the dog has within their life. There are so many types of aggression and therefore, many potential causes. The most common causes include:

  • Fear: Often a dog is aggressive because they’re frightened. This might be directed towards other dogs because they’ve been attacked in the past. It may be towards humans if they’re a rescue dog and have a traumatic past.
    If a dog is put in a situation in which they feel threatened or frightened, such as being cornered, they may react aggressively to try to protect themselves.
  • Lack of socialization: Dogs need to be socialized around other dogs and people from an early age. If they lack this socialization, they don’t learn how to act appropriately around others and may become aggressive.
  • Possessiveness: Some dogs become possessive over toys and food, which is known as resource guarding. They might even become possessive over people. They feel they need to protect these items or people and might do so by displaying aggression.
  • Dominance: Dogs are used to living in packs, within which there is a hierarchy of dominance. If they are unsure of their place in the pack, they may display aggression to fight for dominance (both with other dogs and people in the household).
  • Lack of protection shown by owner: As we mentioned, dogs are pack animals, and you should be the pack leader. This means your dog will look to you for rules, guidance on how to behave, and to keep them safe, which is why training is vital. Without training, your dog might not understand how to behave and sometimes this can result in aggression.

If your dog encounters a ‘scary’ situation, such as a strange dog approaching who they are unsure of or a place or person they are worried about, they look to you for protection and guidance. If you don’t provide that protection, they may feel they need to protect themselves and lash out.

  • Frustration: If a dog is frustrated because they aren’t getting enough physical or mental stimulation, this can build up and can sometimes lead to aggression.
  • Illness or injury: Finally, even the most placid and gentle of dogs can become aggressive if they are unwell or injured. If your dog suddenly starts displaying signs of aggression and it’s out of character, you should always get them checked at your vet to eliminate physical causes.

Other Ways to Deal With Dog Aggression

This all sounds negative but don’t worry, with the right training, socialization, and equipment, aggression can be prevented and dealt with so you and your dog can live a happy life together. As well as collars for control, other equipment can be helpful to keep your dog, other dogs, and people safe.

Muzzles can be useful during training and when out on walks. Harnesses, collars, leads, and lead attachments that are bright colors and state that your dog is nervous or not friendly can let people know they should keep their distance.

While the right equipment can be a helpful tool, the only way to truly tackle aggressive behavior is through training. If you aren’t experienced in training an aggressive dog, it’s always best to do so under the guidance of your vet or a professional dog trainer.

Collar Safety Advice

Always choose a collar of the right size and strength for your dog. Don’t leave your dog’s collar on when they’re in their crate or pen, or during play as this can pose a safety hazard. Avoid prong collars and shock collars, as these can be dangerous especially when used incorrectly.

FAQ

Can an aggressive dog be ‘cured’?

With the right training, aggression can be greatly reduced so that you and your dog can live a happy life together. In some cases, aggression can be overcome completely.

Do shock collars help with dog aggression?

No, shock collars don’t help with dog aggression. In fact, they can increase aggression because they cause physical and mental distress for your dog, as well as ruining the trust between you which is crucial during training.

Conclusion

The right collar can aid you in training your dog and getting aggression under control, allowing you both to relax and make the most of your life together.
