Best dog brands for larger breeds?

I find buying anything large enough for my two lurchers so difficult. Dog coats, dog beds, dog blankets etc. Always seem to cap at a certain size and it’s really annoying. I ordered an “XL” bed last week… and it can just fit my mum’s (pretty small) staffy in it.

Same with coats, especially as they both have minimal hair they never seem to be a good fit AND good quality, always seem to have to sacrifice one of the two.

Can anyone recommend a good brand that does it all? TIA!
