Description
K9 booster block for the K9 sport sacks
Sizing your dog for a K9 Sport Sack® isn’t an exact science. If your dog is in between sizes, has a wide body but short in length, or is still growing, the Booster Block fits snuggly in the bottom of your K9 Sport Sack to boost your dog up 3″. It helps make the K9 Sport Sack experience more comfortable for you and your dog.
FEATURES
+ Constructed of quality foam
+ Removable and washable cloth cover
+ Two blocks may be used to lift up to 6″
+ Excellent to fill in the bottom of the bag for growing puppies who are smaller than the backpack or dog that are between sizes
SIZING
K9 Booster Block are now only available in XS/SM & Med/LG.
For XS and S sport sacks use the XS/S Block
For M and L sport sacks use h=the M/L Block
The XXL boosters are now discontinued. This is because sacks supporting dogs of 23-36kg make a booster block unfit for the intended purpose. The weight of a larger dog flattens the block and will not raise them up in a XL/XXL sack. We do however have a small number of these left to purchase as these fit well into Large sacks for dogs under the XXL weight range.
