Most jackets are available in sizes from small through to extra large. There is no one way to tell which your dog would fit, as there is no standardisation.
However, if you take measurements around your dog’s neck and body, every jacket will have a size guide. Always buy the closest size possible. If you’re on the border of a size, remember that you can loosen them, so go down – a life vest shouldn’t be too tight but also needs to be snug enough to keep them afloat.
Pretty much the main factor of a lifejacket. The best dog life vests will have buoyancy pads around the stomach as well as the sides and back. Also look for flotation around the neck, which will keep their head above water.
A dog life vest should have a handle on the back, so your dog can be lifted out of the water with ease if they are struggling otherwise. It will need to be strong and is especially important for any dogs who are hard of seeing or hearing.
Ideally, it should also be a bright colour so they can be seen – avoid any blacks, greys or dark greens, and you may also want to avoid dark blue.
You can pay anywhere between £20 and £100 for a doggy life jacket. Those at the lower end of the scale will likely not last as long but should still keep your dog floating of course.
Invest if you want something which will last for years, and look for one which can therefore be adjusted.
