Hi there I've gone and looked into this, unfortunately this might be limitations with the software and script being used in the game (That can affect certain computers/devices).
If you encounter this problem you may need to load from an old save / previous save to see if this issue resolves otherwise I've added the bed in the Furniture store and a Merchant that sells all the pets for a low price in case anything like this happens. Apologies for this, hope this doesn't ruin your experience.
