I have a 16 month old dog and a 16 week old puppy (bitch). They got along really wel and played nicely together until this week. My older dog has been unwell for the past week, during which he was too ill to play with the puppy. My dog has now recovered health-wise but is completely disinterested in the puppy. He does not want to pay with her, just ignore her and when she tries to play with him he snaps at her, although not aggressively - just to warn her.

How do I get him to like her again and get them to play and reignite their once harmonious relationship?

Any help is much appreciated!

Thanks
