Outward Hound Granby Splash, Small

Best for: Small dogs with a measured girth of 16–20 inches. This size is listed for dogs of all swimming skill levels and is designed for use around pools, lakes, beaches, or boats.
The vest combines thick foam padding with lightweight ripstop material and reinforced stitching. Adjustable straps and quick-release buckles are intended to make fitting and removal easier. It is a suitable choice when you want a buoyancy vest sized specifically for a smaller dog.
Limitation: The stated girth range is narrow. Measure your dog and consult the size guidance before choosing; do not select by breed or weight alone.
Outward Hound Granby Splash, Medium, Orange

Best for: Medium dogs with a 21–27-inch girth. The listed design aims to provide buoyancy while allowing movement, making it relevant for supervised swimming and boating outings.
Like the other Granby Splash sizes, this vest has thick foam padding, ripstop material, reinforced stitching, adjustable straps, and quick-release buckles. Choose this version if your dog falls within the stated medium girth range and you prefer orange.
Limitation: A medium label does not guarantee a proper fit. Check the vest’s fit on your dog before entering the water and adjust the straps securely.
Outward Hound Granby Splash, Large

Best for: Large dogs measuring 28–32 inches around the girth. Its size-specific fit and buoyancy-focused construction make it a practical option for larger dogs who join family pool, lake, beach, or boat activities.
The vest uses lightweight ripstop material, thick foam padding, and reinforced stitching. Adjustable straps and quick-release buckles help secure it and make it easier to put on or remove. Choose this model when your dog’s measurement fits the listed large range.
Limitation: The listed range ends at 32 inches. Dogs outside that range may need a different size or product; check the manufacturer’s sizing guidance rather than assuming the straps will compensate.
VIVAGLORY Dog Life Vest, Large

Best for: Buyers who want a flotation vest with a top handle, D-ring, and reflective trim. Extra padding is intended to provide buoyancy without restricting movement, while the handle can help with lifting the dog from the water.
The vest has hook-and-loop closures around the belly and neck, adjustable straps, and quick-release buckles. Bright color and reflective trim are intended to make the vest easier to spot. Choose it if those handling and visibility features matter more to you than matching the simpler Granby Splash feature set.
Limitation: The supplied product information does not give a girth range for this listing. Check its size chart before purchase, especially if your dog is between sizes.
Outward Hound Granby Splash, Medium, Yellow

Best for: Medium dogs with a 21–27-inch girth when you prefer yellow over orange. Its listed buoyancy and fit features match the orange medium option, so color is the clearest stated distinction between these two choices.
Thick foam padding, ripstop material, reinforced stitching, adjustable straps, and quick-release buckles are included in the product description. Choose this version if the measurements fit and the yellow color suits your visibility preference.
Limitation: The listed size is for a 21–27-inch girth. It is not a substitute for measuring your dog or checking how securely the vest fits.
Buying Guide: How To Choose A Dog Life Preserver Vest
How should you choose the right size?
Measure your dog’s girth according to the product’s sizing instructions, then compare that number with the listed range. In this selection, the Granby Splash small is listed for 16–20 inches, medium for 21–27 inches, and large for 28–32 inches. If a measurement falls outside a product’s stated range, check the brand’s chart rather than guessing. A vest should fit securely without preventing normal movement.
Which features matter for swimming and boating?
Consider buoyancy, fit adjustments, and how you may handle your dog near the water. The Granby Splash options list foam padding, adjustable straps, and quick-release buckles. VIVAGLORY adds a top handle for lifting, a D-ring for leash attachment, and reflective trim. These features serve different preferences; compare the product details with your planned activities.
Does color make a difference?
Bright colors can help make a dog easier to notice, but color alone does not ensure safety. The listed Granby Splash options come in orange or yellow, while VIVAGLORY describes bright colors and reflective trim. Select a color that is easy to see in the settings where you spend time, and keep your dog supervised around water.
Can a life vest replace supervision?
No. A dog life vest is flotation support, not a replacement for active supervision or safe water practices. Fit the vest before use, check that closures stay secure, and stay close to your dog. The listed products describe buoyancy features, but the supplied information does not establish that any vest prevents every water-related risk.
