Find old pallets in industrial yards or ask your local shop when they have deliveries. That's how we got ours. This was built as a log store but can be improvised to create a shelter for your dog in the warmer months. We constructed this by an outside building which created the back of the log shed.
**Blue painted pallets are unsuitble to burn on a log burner or open fire. The blue paint is toxic. **
Log shed:
1: Decorate with wood paint
2: Add full-length front covering and secure (tarpaulin with eyelets recommended)
3: Add side covering because rain direction is changeable
Dog shelter tweak:
1: Decorate with wood paint
2: On top of the pallet base, lay an insulation roll Optional). This can be bought cheaply from camping stores or The Range. https://youtu.be/4JGuiPBhpHw
3: On the insulation material, add boarding, or old lino and secure
4: Add a comfy cushion - a sponge foam base with a waterproof cover is recommended because of dirty paws. The cover can be removed and washed
5: Cover the top with tapulin or or plastic sheeting, felting, acrylic etc
