Expert sizing advice to ensure the best fit for your growing puppy

Puppies grow like weeds! Ensuring you have a harness that can cater for their growth is important. With up to 5 areas of adjustment, the PerfectFit Harness is designed to offer optimum growth room for your puppy.

Our expert sizing team are here to discuss all puppy size options with you ahead of your purchase. This ensures that we recommend a size combination that offers as much growth room as possible without compromising the fit or comfort for your puppy. We will also advise you on which harness sections you may need to upgrade as your puppy grows.

The PerfectFit Harness provides safe, comfortable support as your puppy begins socialisation and training. Ideal for use with a long line, it keeps your puppy secure while they explore and learn, protecting their neck and ensuring a happy, confident start.

Fitting the harness on your puppy

A stress free design

The PerfectFit harness, unlike many other harnesses is secured around the body, rather than put on over the head. This can make the introduction of the harness less stressful for your little one. With no need to manoeuvre legs into holes, it’s as simple as fitting your puppy in the harness by securing three clips. Welcome to a stress free experience for both you and your little puppy.

When

What age can you put a harness on a puppy?

At PerfectFit, we advocate fitting puppies with a well-designed harness as soon as they are ready to embark on the exciting journey of exploring the world. Puppies, known for their enthusiastic and excitable nature, tend to exhibit a lack of impulse control and are generally keen to play and rush to explore all things new!

This means that, naturally, they will be inclined to pull on their lead. It is crucial to prioritise their health, comfort & safety, taking into consideration their delicate and developing neck area. Although new experiences can be a source of fun for youngsters, some novel environments can be overwhelming and sometimes scary, so using a well-fitted secure puppy harness is essential.

The PerfectFit Harness ensures that your puppy remains secure and comfortable, with minimal risk of escaping, preventing accidents, and providing you with peace of mind.

Why

Why is the PerfectFit Harness ideal for puppies?

The PerfectFit Harness is made up of two or three sections and has up to 5 areas of adjustment. This design allows you to expand the puppy harness as they grow, then replace individual sections of the harness as necessary.

Comfort is an important factor in successful puppy training sessions. The PerfectFit puppy harness is made with soft padded fleece and allows freedom of front leg movement, making for a comfortable and therefore more relaxed puppy.

Unlike collars, which may cause discomfort & potential risk of damage to the trachea and surrounding organs, our harness helps to reduce stress and support the learning process.
