Broadly, you can choose from round or rectangular. The former is great for any dogs who seem to like to curl up and sleep, whereas a rectangular larger shape could be better for any dogs who like to either stretch out or have the option.
Open or Closed
Essentially, raised sides or open? The former is good again for dogs who like to curl up into a ball, rest their head on a side pillow and perhaps love the warmth and being cut off from the world, whereas the former is good for those who like to see everything which is going on and like to be able to pop their paws over the edge.
Just like your human mattress, your dog’s bed needs to be able to take their weight and remain plump and cushioned. But then you also need to factor in the fact that they are in theirs for even longer, and may also be jumping around, scratching and playing in it.
Depending on your dog’s personality, you may need something very sturdy with strong materials and a washable cushion. Materials such as nylon and tweed are great for strength.
Are they worth it, and what are they? While there are no strict rules as to what they are, they are usually filled with memory foam to alleviate pressure on your dog’s joints, and also retain heat to make them more comfortable.
They are usually for older dogs with joint issues such as arthritis or who have just had surgery, but can also help to prevent these issues later in life. If you own a breed who is prone to joint problems, it could help combat symptoms.
