Why We 💚 K9 Booster Block

Sometimes the carrier fits, but your dog could still use a little altitude adjustment. The K9 Booster Block adds about three inches of lift inside compatible K9 Sport Sack carriers, helping shorter dogs sit higher and achieve a more comfortable position without turning sizing into a geometry exam.

- Adds approximately 3 inches of height inside the carrier
- Helps fine-tune fit for shorter dogs
- Useful for dogs between carrier sizes
- Can accommodate growing dogs during certain stages
- Soft block sits securely at the base of the carrier
- Available in two sizes for different K9 Sport Sack models
- Simple accessory with no complicated setup

About K9 Booster Block

Fine-tune your dog’s position inside a K9 Sport Sack with the K9 Booster Block.

Designed to sit snugly in the bottom of the carrier, the Booster Block raises your dog approximately 3 inches so shorter dogs can sit higher and align more comfortably with the pack’s intended fit.

It can be especially helpful for dogs who fall between sizes, have a broad body with a shorter back length, or are still growing into their carrier. The block adds lift without permanently altering the pack and can be removed whenever it is no longer needed.

Key Features:

- Raises your dog approximately 3 inches

- Helps improve vertical positioning inside compatible K9 Sport Sack carriers

- Useful for dogs between sizes

- Helpful for broad-bodied dogs with shorter back lengths

- Can support temporary fit adjustments for growing dogs

- Fits securely at the bottom of the carrier

- Lightweight and easy to remove

- Available in two sizes

Best For:

- Dogs who sit too low inside an otherwise appropriately sized K9 Sport Sack

- Dogs with shorter back lengths relative to their body width

- Growing dogs who need a temporary height adjustment

- Pet parents fine-tuning carrier fit

- Replacing improvised towels or cushions with a purpose-built insert

Sizing:

XS/SM

- Designed for Extra Small and Small K9 Sport Sack carriers

MED/LG

- Designed for Medium and Large K9 Sport Sack carriers

- Can also be used with XL and XXL carriers when additional lift is needed

Height Adjustment: Approximately 3 inches

Metric: 7.62 cm

Compatibility Notes:

- Choose the Booster Block size based on your K9 Sport Sack carrier size, not your dog’s weight alone.

- The Booster Block is intended to refine fit inside a correctly selected carrier. It should not be used to compensate for a carrier that is substantially too large, too small, too narrow, or otherwise inappropriate for your dog’s body shape.

How to Use:

- Place the Booster Block flat in the bottom of the carrier.

- Make sure it sits fully against the base without folding or shifting.

- Load your dog according to K9 Sport Sack’s normal instructions.

- Check that the added height improves your dog’s position without creating pressure against the top, sides, or openings.

- Recheck all carrier straps, buckles, leg openings, and support points before use.

Fit Notes:

- Your dog should remain securely supported without excessive compression or awkward stretching.

- The Booster Block should raise your dog only enough to improve positioning.

- If your dog appears cramped, unstable, overly elevated, or unable to sit naturally, remove the block and reassess carrier sizing.

- Dogs grow and body proportions change, so recheck fit periodically rather than assuming yesterday’s setup is now a binding legal precedent.

Safety Notes:

- Use only with compatible K9 Sport Sack carriers.

- Inspect the Booster Block before each use for tears, compression damage, exposed filling, or loss of shape.

- Discontinue use if the block becomes damaged or no longer sits securely.

- Do not allow your dog to chew or ingest any part of the Booster Block.

- Always confirm that your dog’s breathing, posture, and circulation remain unrestricted while using the carrier.

- Supervise your dog whenever they are inside the carrier.

- For extended travel or activity, allow regular breaks and reassess comfort throughout use.
