They say every dog has its day - and one political pooch had hers during prime minister's questions.
It wasn't Dilyn, Boris Johnson's Jack Russell cross, however, but Maisie the collie, the SNP Westminster leader Ian Blackford's dog.
As Mr Blackford, appearing virtually from his home on the Isle of Skye in his constituency, attempted to put the prime minister in the dog house over sleaze and cronyism, Maisie could be heard barking loudly during his questions.
MPs in the chamber howled with laughter, but the prime minister, whose shaggy dog hairstyle gives him the appearance of a highland sheepdog at times, couldn't resist bringing Mr Blackford to heel.
Claiming the SNP MP was barking up the wrong tree, Mr Johnson said: "I thought his dog just made a more sensible contribution to the discussion than he did."
Later Mr Blackford tweeted: "The three million people left behind by his government didn't have a David Cameron or a James Dyson to text the PM for them.
"Even my dog Maisie knows that."
And in more dog whistle politics, Mr Blackford also tweeted a photo of himself with his hound, claiming she was barking mad with the prime minister.
"Here is the offending Maisie, who seems to want to call out the behaviour of Boris Johnson," Mr Blackford growled.
Well, they do say that in politics it's dog eat dog.
