Pets that fall in the "High Energy Level" category:
Need at least 90+ minutes of activity/day to keep them happy and healthy.
This includes longer walks, more playtime, and more enrichment/puzzles. Your dog is likely high energy if they are a working, sporting, herding, or terrier breed/mix.
This can also apply to any dog that needs regular off-leash time or plays with other dogs often (we can't offer these things, so will spend more time playing and walking with them to compensate).
