I had a 7 month old pup that went swimming this summer, He would only go in up to his elbows, and I did not want to force him in the water.. I tried food, toys, me.
Other dogs to entice him in.
Nothing worked,
Than we went a second time and he got a little braver, but I also put on a vest again, he went in further but ran out.
The third time I went, I threw a pine cone in the water and bam, he went after it, and that is what it took for him..
Never use force, that will only scare them.
I did keep a long line on mine as well.
Swimming really tires them out and if they are not in good condition you must be careful as well.
I also made sure he did not sink, the first time he learned and was using his rear end as well to propel, once his life vets was off.]
I have seen one field line golden in the water after awhile almost drown. Not all dogs are born natural swimmers!!! Owner had to swim in and retrieve the retriever. Dog ended up swallowing alot of water and getting very sick.
I am sure others might have some advice as well.
