the problem with my CAO Volka is that he already tore apart two beds and he has a tendency to eat the stuffing. i spent lots of money on the last one and he only used it for a month. so now i have all his area padded with thick rubber mats that are used in the gym, covering closely and tightly all his living area so he cannot hold on to a corner and start chewing it, besides these are very thick,,,so he just sleeps on them. The weather here is very mild so no need to any covers or anything like that.
my other dog Bono the bichon just sleeps wherever he pleases and most of the time on my bed.
Lately my vet got some really heavy duty impermeable thick beds for dogs made in Italy i think but they are too expensive like around 250 dollars the big one for Volka, but i am not taking the risk....
