Swimming vs Walking: Which Is Better Exercise for Your Dog?

This gets asked as though there is a winner. There is not. Walking and swimming do different things, and most dogs are better off with both than with a lot of either.

What walking is good at

Walking is the backbone. It is free, it is daily, it builds steady fitness, and crucially it is where most of your dog's mental enrichment happens. Sniffing a hedge for ten minutes tires a dog more than most owners realise. Walking also loads the bones and joints in a way that keeps them strong.

What swimming is good at

Swimming takes almost all the load off the joints while still working the whole body hard. That combination is unusual, and it is why swimming suits three groups particularly well: dogs carrying extra weight, older dogs whose joints protest at distance, and high energy dogs whose owners simply cannot walk far enough to tire them out.

It is also far more tiring per minute than walking. Twenty minutes of real swimming will empty a dog that an hour on the lead barely dents.

Side by side

• Joint impact. Walking loads the joints, which is usually good. Swimming almost eliminates loading, which is better when joints are the problem.
• Energy burn per minute. Swimming wins comfortably.
• Mental enrichment. Walking wins on sniffing and variety. Swimming wins on novelty and problem solving.
• Weather. An indoor heated pool is identical in February and July. A walk is not.
• Cost. Walking is free. Swimming is not.

The practical answer

Keep walking daily. Add swimming when you want to take pressure off the joints, when the dog has more energy than the walk can absorb, or when you want something genuinely new for them. For most households that is once a week or once a fortnight rather than instead of anything.
