Nina Ottosson Challenge Slider Review: A Difficult Dog Puzzle Toy for Experienced Dogs

The Nina Ottosson Challenge Slider is a difficult dog puzzle toy that requires more than simply finding a treat compartment. A dog must move the sliding pieces into open spaces to reach every hidden treat. Based on our experience, it is best for dogs that already understand basic food puzzles and continue working when the solution is not immediately obvious.

What Is the Nina Ottosson Challenge Slider?

The Challenge Slider is a flat dog puzzle with multiple covered treat compartments. Instead of lifting a lid or flipping a single piece, the dog must push the sliding covers across the board.

The important detail is that each slider cannot move freely in every direction. The dog has to use an available empty space and move the pieces in sequence. The basic idea is similar to a sliding tile puzzle for people.

This structure makes the toy more complicated than puzzles where a dog can open each compartment separately. Smelling the treats is easy. Reaching them requires repeated pushing, pawing, and repositioning.

Difficulty Level and Learning Curve

The Challenge Slider is labeled as a Level 3 puzzle in the Nina Ottosson line. That classification matched our experience. Louie could smell where the treats were, but understanding how the entire sliding system worked was much harder.

During his first sessions, he did not appear to plan several moves ahead. He relied on persistence and physical effort. He pushed the covers repeatedly until one moved into a useful position.

His speed gradually improved over multiple sessions. However, improvement did not always mean that he fully understood the puzzle like a person would. He may simply have learned which pushing motions were more likely to expose a treat compartment.

That is still a useful form of enrichment. A dog does not need to solve the toy in a perfect or elegant way to benefit from sniffing, experimenting, and staying engaged.

How Louie Used the Puzzle

Louie is a small Yorkshire Terrier who rarely takes a break once a food puzzle begins. He continues searching until every treat is gone.

The Challenge Slider held his attention longer than several simpler nose work toys. When a cover would not move, he did not walk away. He pawed at it, changed positions, and tried again until he reached the food.

His approach was energetic rather than careful. Dogs that use their paws forcefully may make repeated tapping or scraping sounds against the plastic. The toy should therefore be used on a stable surface where it cannot slide easily.

Supervision is also important. It allows the owner to prevent chewing, stop the session if the dog becomes frustrated, and confirm that all treats have been removed before the toy is stored.

What We Liked

  • It created a different challenge: The sliding movement was different from Louie’s puzzles with removable lids or simple openings.
  • It held his attention: He continued working even when the next step was not obvious.
  • It can be reused in different ways: Treats can be placed in fewer compartments during easier sessions or spread across the board for a longer activity.
  • The base can be removed: Pulling out the bottom section makes it easier to reach crumbs trapped under the sliding pieces.
  • Cleaning was manageable: We could rinse the treat areas instead of trying to clean each narrow compartment from above.

What to Check Before Buying

This puzzle may be unnecessarily difficult for a dog that has never used an interactive toy. A beginner may do better with a puzzle that uses large removable covers, open cups, or one-step movements.

The Challenge Slider may also be a poor match for dogs that immediately bite plastic parts when food is difficult to reach. It is designed for supervised puzzle sessions, not for unsupervised chewing.

Owners should also consider how their dog reacts to frustration. Persistent dogs may enjoy experimenting. Dogs that quickly become agitated may need shorter sessions, fewer hidden treats, or help moving the first slider.

Who May Enjoy This Dog Puzzle Toy?

The Nina Ottosson Challenge Slider may work well for:

  • Dogs that already solve basic treat puzzles quickly
  • Dogs that remain interested in a task for several minutes
  • Dogs that enjoy pushing objects with their nose or paws
  • Owners who rotate several puzzle designs instead of using one toy every day

It may not be the best choice for:

  • Dogs using a food puzzle for the first time
  • Dogs that chew or damage plastic puzzle pieces
  • Dogs that become highly frustrated when food is inaccessible
  • Owners looking for a toy that can be left out without supervision

Final Verdict

The Nina Ottosson Challenge Slider gave Louie a more demanding activity than his simpler nose work toys. He did not always use a clear strategy, but he stayed engaged and eventually found every treat.

Its strongest feature is the sliding structure, which creates a different problem from lift-and-open puzzles. The removable base also makes cleaning easier than the complicated top design initially suggests.

This is not the first puzzle toy I would choose for a complete beginner. For a persistent dog that already enjoys finding hidden food, however, it can add a useful new challenge to a rotating collection of dog enrichment toys.
