Reward-Based Dog Training in Portland, OR


Your dog is more than just a pet—they’re part of the family. But to truly thrive, dogs need more than food, shelter, and love. They also need guidance, structure, and mental stimulation. When dogs get the right training, they can overcome behavioral issues and live peacefully and happily with their families.

At Maniac Mutts, we specialize in helping dogs and their people find that balance. Whether your dog is struggling with fear, anxiety, or aggression, we use kind, positive training methods to help them learn, grow, and thrive.

We know how tough it can be when your dog is dealing with issues like barking, leash pulling, or jumping up on guests. These challenges can make everyday life stressful, but we’re here to help. With our experience and compassionate approach, we can guide you and your dog to a happier, more peaceful life together.

Whether you're looking for help with puppy socialization, leash training, or more complex behavior problems, Maniac Mutts is here for you.
