It's a decent mid-game card with moderate stats and an ability that adds a random Dog into your hand. However, unlike Alphys, the gained card doesn't get a drop in cost. The Dog House also can't attack, but it does have Taunt.
It is a good card for it's stats. It could be used with Doggo if you get it from the Dog House to send it back then get another dog. Due to it having Taunt, it can also be used as a strong wall. Increasing its ATK with Strength, Aaron's Secret or Snowdrake also prevents it from dying to Muffet's Pet.
