K9 Booster Blocks for K9 Sport Sack Dog Backpacks
Lightweight, soft and sturdy booster blocks to help you and your adventure dog get the perfect fit with a K9 Sport Sack dog backpack.
The blocks are designed to fit snuggly into the bottom of the full range of K9 Sport Sack dog carriers, based on bag size. Each block will lift the dog by 3", making them ideal for wide body but short in length dogs or those still growing. Not every dog is the same size and shape, but these will help you get the most comfortable and safe fit when needed.
K9 Sport Sack Booster Block
The booster pet block is made of high quality foam that is built to last. Dogs can be messy, that is why each block comes with a removable and washable cloth so you can wash off any mud or dirt.
- Made of quality foam (soft and light)
- Removable and washable cover included
- Can be doubled-up for a 6" lift
Small Booster Block and Large Booster Block
Extra Small/Small Booster Block: Adds 3 Inches of Height to a Small or Extra-Small TRAINER, AIR-2, PLUS-2, KNAVIGATE, or URBAN-2 model. For Shorter, Thicker Dogs or growing dogs. Weight = approx. 120g
Medium/Large Booster Block: Adds 3 Inches of height to a Large or Medium TRAINER, AIR-2, PLUS-2, KNAVIGATE, or URBAN-2 model. For Shorter, Thicker Dogs or growing dogs. Weight = approx. 120g
* Also compatible with XL and XXL backpacks if necessary. XL booster blocks and XXL booster blocks have been discontinued.
Can the K9 Sport Sack booster blocks be used with other dog backpacks?
These booster blocks have been designed especially for the K9 Sport Sack range of dog backpacks, they could therefore be unsafe if used with alternative doggy backpacks and we would therefore not recommend it.
How to choose the correct K9 Booster Block size?
Double check the size of your K9 Sport Sack Backpack. The sizes of the booster blocks correspond to the sizes of each dog backpack.
How to use a K9 Booster Block?
Once the correct size is picked and arrives, simply slide into the bottom of your K9 backpack, ensuring it fits snuggly and without gaps at the side.
Does this come with a K9 dog backpack?
This product only contains the K9 Sport Sack Booster Block. The K9 Sport Sack bag is sold separately and is not included in this purchase. The booster block is designed to be an accessory for the pet carrier backpack that will help make your pup more comfortable.
Can this be used as a puppy booster block?
Providing the related bag size/weight restrictions and guidance has been followed, these are suitable for a range of dogs small-large.

Latest recommended posting dates for Christmas (national and international) can be found here.
Before placing an order, please ensure you have read our full shipping policy below and reach out to us at firstname.lastname@example.org if you have any queries.
Coronavirus Update: Due to current events, we would recommend a tracked service is selected. We are continuing to process and dispatch our orders on time however due to the pandemic there may be delays experienced throughout postal networks, both nationally and internationally (especially at the customs stage) due to reduced air capacity, high mail volumes and COVID reduction measures. We will do everything we can to work with our couriers and ensure as fast a service as possible, but during this time are unable to guarantee usual shipment time frames and delivery windows. More can be found on our Covid policy here.
- We fulfil and ship orders daily, Monday-Friday excluding bank holidays.
- Our same-day dispatch aim* cut-off is 12pm UK time. We recommend contacting us if this is required, since it is not a guaranteed service.
- We fulfil and ship the vast majority of orders within 1 working day, however during peak periods this process may take longer and does not include preorders/backorders. Please therefore let us know if you need your order in a hurry!
- All shipping timelines provided are delivery aims unless otherwise stated and do not account for delays outside of our or our couriers’ control such as bank holidays, adverse weather conditions or customs processing times.
- We offer free Tracked-48 hour delivery for spends over £75 within the UK.
- Basic shipping estimates (average parcel weight 250g-1500g):
- You must ensure the correct address format and contact details are provided to us at the time of order and that you are not purchasing restricted items for the destination country to aid with prompt delivery.
- You as the customer are responsible for your own countries customs duties and taxes charged at the time of customs release, delivery or collection.
- In the case of failed delivery due to incorrect address information or contact details being provided, customs duties not being paid, or restricted items being purchased, no shipping refunds and/or compensation will be provided as per our returns policy.
When do we ship?
We fulfil and ship orders daily, 5 days a week (Monday-Friday) excluding bank holidays. Although we fulfil and ship across most of the week, please note we have a same-day dispatch cut off time (below) plus some couriers and manufacturers/suppliers have fluctuating non-postal days, such as weekends. Therefore any orders made after 4pm UK time Monday-Friday may process that day but will not start shipping until the following working day.
*Same day dispatch aim
Order before 12pm UK time, Monday-Friday for our same-day dispatch aim. We recommend contacting us if this is required, since it is not a guaranteed service. Our same day despatch does not include personalised items such as pet tags, pre-order/backorder items or items which require shipment directly from the manufacturer or supplier. Orders including the above may be placed on-hold or shipped separately.
Pre-order and backorder items
Upon a pre-order item or backorder item being purchased (as listed on the product page), the order is placed on-hold until the item arrives to us and the order is then shipped ASAP. Updates will be provided along the way including the estimation and as always, confirmation will be sent once the item has shipped. Further information on pre-order and backorder items can be found here.
All shipment timelines provided within this policy are delivery aims unless otherwise stated as guaranteed. When there are scenarios outside of our or our couriers’ control such as national and international bank holidays, adverse weather conditions or country-wide border changes/extended customs processing times, there may be a risk of delays in delivery to the destination. We are unable to offer refunds or compensation for "late" deliveries in these circumstances.
Free delivery bands*:
Once the minimum order spend has been met for the country you require shipment too, the free delivery band will become available in your basket.
These bands are:
UK – Spend over £75 to receive free Tracked-48 hour UK delivery (2-3 working day aim)
*Same day dispatch and free delivery is not currently available on Animalarm, Ruff&Tumble drying coats, Petsports (Outside of the US), Canine&Co Christmas pet jumpers and may exclude bulky/heavy items, out of stock items/pre-orders or items which require shipment directly from the manufacturer. When additional charges are required (such as for the above products) these will be displayed in the basket at the shipping calculation stage. All items which require a separate delivery charge will still count towards the free delivery bands but may add a 3-5 day delay to the order dispatch date.
Travfurler Ltd reserve the right to amend or cancel these bands at any given time.
Shipping calculations & charges
Estimates can be found within this policy (at the bottom), however due to the calculations required around weight and specific delivery address, the most accurate place to check is the shipping calculation stage within checkout. For this simply add your items to basket, input your address and the delivery charges will automatically update allowing you to select your preferred method.
Address formats, contact details & restricted Items
You must ensure the correct address format and contact details are provided to us at the time of order and that you are not purchasing restricted items for the destination country. We will always endeavour to check for potential issues; however, we cannot be held responsible for incorrect address data, incorrect contact details or restricted items being purchased. Should one of these scenarios occur, there will be no refund or compensation provided for shipping costs (original, return and/or re-posts) nor for scenarios where customs may dispose of parcels. The best way to check you are meeting the destination countries shipping guidelines is to check the relevant shipping guide found here: Country guides.
Customs duties & taxes
Since we have no control over country border charges, we are unable to estimate customs duties and taxes within our product or shipping pricing currently. Therefore, you as the customer are responsible for your own countries customs duties and taxes charged at the time of customs release, delivery or collection. Please bear this in mind when placing international orders. If you are unsure on whether you will be subject to customs fees, we would recommend contacting your local customs office for more information before placing your order. If you choose to refuse the customs fees and the parcel is returned to us, the shipping costs will not be refunded, and a handling fee may be deducted from your refund.
National Customs Websites can be found here for information purposes.

- If the product returned is not in a fully resalable condition or the packaging is damaged, we reserve the right to refuse a refund on the item or offer a partial refund. This does not affect your statutory rights and excludes incorrect, faulty, or damaged upon arrival items.
- All refunds will be processed using the same method of payment used to place the order.

Then contact your debit/credit card company, since it may take some time before your refund is officially posted.
If they are unable to help you will need to contact your bank since there is often some processing time before a refund is posted.
Finally, if you have done all of this and you still have not received your refund yet, please contact us at email@example.com so we can investigate.
If you have any questions around this policy, please reach out to us at firstname.lastname@example.org.
Sometimes we list items as out of stock, but available on preorder or backorder. This allows you to have a first look at what's due to arrive to us, snap up something you might be waiting for or place a direct order for a specific item you can't find anywhere else. The aim of this guide is to help explain the two terms and give an idea on timelines plus answer other frequently asked questions around these status'.
Preorders (ETA: As per the due by (XX-XX-XX) date listed):
When an item is listed as 'COMING SOON! XX-XX-XX preorder', this item is on it's way to us and available to purchase on a preorder basis. This means you are able to purchase the item before it arrives to us, thus ensuring you are the first in line to receive it. The due by date is given as an approximation on when the item should arrive to us, thus giving an idea on when the item will ship onto you. Once the purchase is made, the order will be placed on-hold until the pre-ordered product arrives and can be shipped on (via the shipping method selected at checkout).
Backorders (ETA: Usually 1-2 weeks):
When an item is listed as 'OUT OF STOCK! Available on backorder', this means the item will be added to our next order placed with the related supplier once your purchase is made. Which means you are able to purchase exactly the colour/size/style item you would like, even when out of stock with us. Usually this is a 1-2 week process however it is always best to check with us at email@example.com before purchase for a more specific timeline since stock levels and frequencies fluctuate throughout the year. Once the purchase is made, the order will be placed on-hold until the back ordered product arrives and can be shipped on (via the shipping method selected at checkout).
Our aim with offering these two services is to help us provide you with the exact products you want and love as well as making our processes as transparent as possible.
We hope this breakdown is useful, however if you do have any further questions please reach out to us as we're happy to help!
