I bought this for the dog and she loves it (retrieval rather than catch). I thought the plastic would be too hard compared to a rubber Kong but something about it really excites her. The lights are great but I wish they had an option to stay on, or dimmed, when not being thrown. If she drops this in the dark I’m unlikely to find it (there is a ‘flash when lost’ feature but I don’t think it’s as reliable as ‘always on’). What I’d like to see is a dog version of this – softer plastic, a simple on/off switch, an always ‘dim’ option – but until then this is the best I have tried
