B20 Single Dog Cage

for your Discovery 1

The best boxes on the market! This is my second box only because I had gained a few more K9 friends and I am over the moon. The service is second to none with the most helpful and professional staff. I use my vehicle for competitions, working and demonstrations so to know my team are completely safe during transport and being away is utmost important to me and there’s no other box I would use!

B20 Single Dog Cage

for your Discovery 1 1992-1998


Fantastic customer service & product. Placed my order Sunday & received a call Monday morning to discuss the size of my dog to make sure she would be comfortable as I have a 2019 Mercedes A Class which has a strange shaped boot. Was really impressed, most companies would just take your money & not care. Highly recommend
