The Dog House at Christmas
8pm, Channel 4
Tissues at the ready for this festive special of the rehoming show filmed at a Woodgreen animal centre. “Never had a blind date with a dog before,” says Lynne (above), a 62-year-old nurse whose kids have left home. “Can’t be any worse than a two-legged one.” (Unless, she adds, it’s Gerard Butler.) But will the west highland terrier Jock click with her? Elsewhere, little Elena wants a doggy friend because she feels left out by her older twin brothers – might a shih‑tzu called Lexi cure her loneliness? Hollie Richardson

Film choice
Asteroid City (Wes Anderson, 2023), Prime Video
Wes Anderson’s style has become more well known than his movies, with Instagram accounts and fan films riffing gleefully on his colour-coordinated sets and deadpan comic characters. His new feature won’t disappoint in that respect, as a 1950s town in the US desert plays host to a Junior Stargazer convention. Attenders include Jason Schwartzman’s widowed war photographer, Scarlett Johansson’s film star and their respective offspring – plus a very unexpected visitor. Simon Wardell
