Scratch Board Training
What is a Scratch Board?
Scratch board training is a great way to decrease a dog’s nail length without having to restrain your dog or worrying about cutting their quick. A scratch board is simply a piece of wood, a cutting board, or a piece of PVC pipe covered in an abrasive material such as grip tape or sandpaper. You train your dog to scratch at the surface, filing down their nails in the process. This skill can be especially useful for dogs who are uncomfortable with nail trims, handling, or restraint.
Scratch boards can be purchased premade from various sources, including Amazon and Chewy, or you can make one yourself.
60-80 grit sandpaper is ideal for large dogs. 100-120 grit is ideal for small or sensitive dogs.
You will need:
Scratch board
Can be premade.
or
Can be made yourself using a rigid surface and an abrasive material.
Rigid surface - A piece of wood, a cutting board, PVC pipe, etc.
Abrasive material - Sandpaper or grip tape. Can be self-adhesive or affixed with a spray adhesive.
Treat pouch
Clicker (or other conditioned marker)
A supply of small treats
Tips and Tricks:
Using a scratch board should be a fun game for your dog! The board should essentially become a treat slot machine.
The end-goal cue for this behavior (in these instructions) is the visual presence of the scratch board. This means that it should be put away in between training sessions.
Keep sessions short! No more than 5-10 minutes at a time. Rest, recovery, and play in between sessions is important for the learning process.
It may take several sessions to proceed to the next step, don’t feel discouraged if your dog doesn’t get it straight away! If one method doesn’t seem to be clicking, give a different one a try! The more ways your dog can come to the conclusion of scratching the board, the stronger the behavior will become.
Alternatively, your dog may surprise you and blow through the steps!
Work with your dog, not against them. Keep individual preferences in mind and adjust accordingly.
Get creative! Don’t be afraid to experiment with different surfaces and reinforcers.
Work sessions into your daily schedule - ex. do some scratch board repetitions every night before dinner.
Your dog may favor one paw over the other. If this becomes problematic, you can work on shaping scratching specifically with the non-dominant paw, then practicing alternating between the two.
Method 1: Shaping
For dogs who are already clicker trained -
Before you bring out the scratch board, be prepared to click and treat your dog’s first investigation of the scratch board.
If your dog is suspicious of the scratch board, instead click/treat your dog for first just looking at the scratch board, then for moving closer to the scratch board, before moving on to the next step.
Place the scratch board on the floor (be sure to place it on a non-slip surface or to hold it in place to avoid scaring your dog), and click/treat when your dog touches their paw to the scratch board.
If your dog offers an alternative behavior such as nosing, refrain from reprimanding them. Simply remain quiet and refrain from clicking until they show deliberate paw movement, then work on shaping closer proximity to the board.
Repeat Step 2 several times, then begin gradually increasing the incline of the scratch board. Specifically click when your dog’s nail(s) make contact with the sandpaper.
Some dogs find the sensation of the sandpaper to be strange and may take multiple sessions to gain the confidence to confidently touch it. Don’t force things, let your dog advance at their own pace.
Selectively click when your dog’s nails scrape across the sandpaper.
Once your dog is reliably scratching, begin clicking at random intervals or for particularly good scratches.
Be sure not to stretch the intervals out too long, as this could frustrate your dog and cause them to lose interest in the “game”.
Method 2: Luring
For dogs who are not afraid of the scratch board -
There are products available that are covered in an abrasive surface and have a compartment you can put treats in to encourage your dog to scratch at it. For some dogs, this can be a good way to file nails down without much training effort on our part. Other dogs may not be motivated to paw at them without some prior conditioning, or may find this approach to be frustrating to the point of displeasure. If scratching does occur, a clicker can be used to capture the behavior.
Use a food lure or hand target to guide your dog to step onto the scratch board (laid flat either on a non-slip surface or being held in place). Click the moment your dog’s paw touches the board and toss the treat away, resetting for another repetition.
After 3-5 repetitions, fade the food lure by motioning as if you have food in your hand, but without actually having food in your hand. Continue clicking and treating your dog for touching their paw to the scratch board for another 3-5 repetitions, then work on fading the hand motion by making less exaggerated movements until your dog is touching the board with their paw without any hand movement occurring on your part.
Increase the incline of the scratch board gradually. Click and treat your dog for touching their nail(s) to the board, then for scraping their nail across the sandpaper. Continue clicking and treating for more exaggerated scratches.
Method 3: Transferring
For dogs who already know a paw target or “shake” cue -
Cue your dog to target your hand with their paw while it is over the scratch board. “Dump” your dog’s paw onto the scratch board and click/treat when it makes contact with the board.
Start fading your hand. Cue the paw target with your hand in place, but move your hand out of the way before your dog touches it. Click and treat them for instead touching the board.
Fade the verbal cue and instead motion toward the scratch board, clicking and treating for any contact. Continue fading the hand motion until your dog is touching the scratch board on their own without any hand motion on your part.
Like with the previous methods, you’ll increase the incline of the board and work on shaping a scratching behavior.
