I'm looking into purchasing a dog life jacket for kayaking with our Shetland Sheepdog puppy, when he is fully grown (6months, he's currently almost 4months).
Ideally this will be for rough water such as the sea, as potentially on calm water like the canals he may be ok swimming. However he is long haired so swimming may get tiring without the jacket for him.
When looking for my own life jacket I found the safety ratings confusing (first time purchase!) Do dog life jackets have the same / similar ratings to human life jackets?... Also What rating would be recommended for a mix of sea, canal and lake activity?
Edit: here he is in his new jacket
