Ah yes found it now and it is a little selective in it's context.

But as for your point about shouldn't he be discussing more important things here's where the context comes in; he was speaking to a french newspaper and he discusses how talks are going on the important points for the EU; Rights of Europeans and UK citizens in Europe, Northern Ireland, The Divorce Bill. He then gets asked a question about
The lack of agreement, the "no deal", is more and more openly evoked in London ...
and in his reply explaining that a no deal brexit would have consequences on many domains he uses the example of pets after a larger one of planes
'Without agreement, it would fall into the common law regime of the World Trade Organization, with relations similar to those we have with China. A failure of the negotiations would have consequences on multiple domains, just on the ability of British planes to land in Europe, the United Kingdom leaving the single sky, or on dogs and cats to cross the Channel! In Europe, everything is integrated because we have common standards: that seems to have been forgotten.'
