Dagshund has slow movement speed but attacks non-stop with high damage and Area Attack, but his slow attack animation and short range balances this out. He isn't intimidating alone, but he is usually spawned in groups or just spawned rapidly when included in a level. However, in later stages, due to his single knockback, this enemy will often be used as a wall with high HP, such as in Pecking Order.
Dagshund attacks non-stop and has a strong Area Attack. However, this enemy has a fairly slow attack animation, so it is pretty hard for him to advance. The best thing to do would be to spam defensive units (Cat, Tank Cat, etc...) while having Bahamut Cat take him out. Stacking Lizard Cats or Salon Cats can also work if you have enough meatshields to stall the Dagshund.
