[quote=@The Mighty Hero] I'm not sure off the top off my head what kind of attacks they can perform. I'll have to check the PHB and DMG. [@JBRam2002], do you happen to know if there is a governance on attacks companion animals can perform? [/quote] The Mastiff can be found [url=https://roll20.net/compendium/dnd5e/Mastiff#content]here[/url]. I would suggest that if these dogs are simple companions without significant training that they would be unlikely to attack if they are in danger without an Animal Handling check. If they have had training (which likely would have increased the cost of purchase), then they should be okay to run into obvious danger in most cases. Either way, they would likely defend themselves and their Master unless the Master uses one of his Attacks to command one of his minions to attack. I know that sounds pretty harsh, but tossing in 4 companions on a single person is extremely powerful. Each companion can grant flanking bonuses simply by existing. If you use the original Beast Master Ranger, the above is what's recommended (there are lots of explanations why). 5e doesn't really have many rules for untrained companions, so I'd suggest looking at Pathfinder's [url=http://www.d20pfsrd.com/skills/handle-animal/]Handle Animal[/url] page for what previous versions did. Keep in mind that the DCs are much higher in Pathfinder than in 5e. Also in response to a previous post: you said that the guards have been trampled. Does this mean they are prone? If so, it takes half their movement speed to stand up from prone.
