dog track

HI all! I’m Justin and I’ve got two medium dog breeds at home. I’m really into spending time with them on the beach and they love going into the sea and cooling down in. The beach which we usually stay, is really rough in regard to the swell. Even though they’re quite good swimmers and have good qualifications to  go in and leave the sea easily, I’m really trouble by this issue. I care someday one of them won’t leave the sea so easily… L well, I was wondering about if there’s any sort of dog collar for avoiding these situations. I was told about dog life jackets but I’d like someone to tell me something about them. Thanks in advance
