There are many fun activities you can do with your Newfoundland dog! Swimming is one of their favorite activities since they have webbed feet which make them excellent swimmers; take them out for a dip at your local lake or beach! Hiking is another great way to get some exercise while spending quality time together; find trails near you that are suitable for larger breeds like Newfoundlands so that your pup can enjoy exploring new places without getting too tired out too quickly! And lastly, don’t forget about playtime – fetching games are always fun (and tiring!) for both you and your furry friend!
