I would not say definite no to clipping this dog, I would ask why the owners want him clipped...
I would never clip a dog like that if it was not necessary but we do clip our oldie in the summer!
She is a ten year old Leo and has a tendency to get hotspot and she does got so hot and bothered in the warn summer days!
Few years ago we decided to clip her and have not looked back, she now gets a summer look every summer!
If she had her full coat on she would not be able to go swimming as much as she does as even with a shower to clean her and the coat blown dry she seemed to hold some moisture and end up with a hotspot in certain areas (these areas were obviously dried extra carefully).
Even when she was banned from swimming (other problems) she would drink and lay in the water and because of the hot weather end up with hotspot in her neck! But she does have very sensitive skin and immunological problems so this plays a part in her sensitivity.
She does not look as good as she would look and I actually love grooming the coat (its my therapy :) ) but she is so much cooler and happier in her short coat(even though people say the can keep them cool this definitely was not a case with her!)
For her quality of life she gets trimmed short as this allows her to keep cooler and enjoy her retirement years to the full!
You can actually see her getting happy when we are clipping the coat off and she does rounds running (this dog hardly ever runs!) showing off her clipped cooler look!
She still grows a proper coat for the winter and the quality of this coat has not suffered at all from the "summer" look as the clipped coat gets blown in the autumn.
