Brawler’s Best Friend

Starting when you choose this fight club at 3rd level, you gain a hound that accompanies you on your adventures and fights alongside you. It is friendly to you and your companions, and it obeys your commands. See its game statistics in the Hound stat block, which uses your proficiency bonus (PB) in several places. You determine what breed of dog, or similar canine creature, your hound is; your choice has no effect on its game statistics.

In combat, the hound shares your initiative count, but it takes its turn immediately after yours. It can move and use its reaction on its own, but the only action it takes on its turn is the Dodge action, unless you take a bonus action on your turn to command it to take another action. That action can be one in its stat block or some other action. If you are incapacitated, the hound can take any action of its choice, not just Dodge.

If you spend a minute giving your hound attention and treats, it regains 2d6 hit points. If your hound has died within the last hour, you can revive it by coaxing it back from the threshold of the beyond with praise and pets. You can use an action to touch the hound and expend a number of Hit Dice equal to half your pugilist level to revive it, provided you are within 5 feet of it. The hound returns to life after 1 minute with all its hit points restored. If your hound dies or is otherwise unavailable to you, you can forge a bond with a dog over 8 hours to become your new hound, ending your connection to your previous one.

Hound - Dog & Hound Pugilist Subclass Monster Statblock

Mutt With Moxie

Starting at 3rd level, you share everything with your faithful hound: food, shelter, even moxie. When you use certain moxie abilities, your hound gains a benefit as well.

• Brace Up. When you gain temporary hit points as a result of using your Brace Up moxie ability, your hound gains the same number of temporary hit points.
• The Old One-Two. When you use your The Old One-Two moxie ability, your hound can make one or both attacks instead of you.
• Stick and Move. When you use your Stick and Move moxie ability, your hound can take the Dash action.

Coordinated Attack

Starting at 6th level, you and your canine companion form a more potent fighting team. When you use the Attack action on your turn, if your hound can see you, it can use its reaction to make a bite attack.

Hound’s Best Friend

Starting at 11th level, when a creature deals damage to your hound with an attack, you can use your reaction to make an opportunity attack against that creature if you are within range.

Off the Chain

Beginning at 17th level, your hound’s spirit is as unbreakable as yours. When your hound takes damage that reduces its current hit points to half its maximum hit points or less, you can use your reaction to let your hound off the chain. When you do, it immediately gains temporary hit points equal to four times your pugilist level and, for the next minute, its speed increases by 15 feet and it can take the bite or Dodge action (your choice) each turn you don’t command it. Once you use this feature, you can’t use it again until you finish a long rest.
