We have a nearly 10-year old smallish collie (she's 17.5kg) who has arthritis in her hips and one hock. I'm thinking about getting her a better bed as hers is old and a bit smelly tbh, and looked at some orthopaedic ones. They range a lot in price and I'm really not sure what to go for - I can't afford to spend the £250 odd that some of them cost (could go up to £150 at a push but would prefer £100 or less if possible). Does anyone have any comments, suggestions, recommendations? She likes to sleep on her back so quite enjoys a raised edge to prop herself up against.
TIA
