@RichardBuddLake Thanks for reaching out!
We're sorry to hear that your previous boots have worn out. Although you are putting on a good amount of miles on them, sometimes if a boot wears out too quickly that can be a sign of poor fit. We would recommend signing up for a virtual outfitting appointment with one of our footwear experts. They can talk to you in more depth about your feet (wide, narrow, high volume, etc), needs (bunyons, morton's toe, significant difference in size, etc), and any issues (including your boots wearing out) you may be experiencing. They can then make a recommendation based on that information.
In the meantime, if you'd like to take a look at a couple of styles of boots that are known for their durability and may fit your needs, here a couple of options:
Also, feel free to post some pictures of your pup in this thread!
Hopefully this helps!
