I have a sighthound x collie or spaniel of some sort. She has a fluffy coat but it’s quite close-laying. She’s built more like a greyhound and is naturally very lean and slim, so doesn’t have much insulating fat.
I’ve just ordered her a Bucas Freedom – it has the bib that goes between their front legs and then you clip it around their belly, much like a harness. The clip sits quite far back, where her tummy tucks up, so I’m optimistic on the fit. I haven’t found much else that works on her.
It should be arriving in the next 2-3 days, so I’ll update! They have a 50g and a 300g. So far I’ve only ordered the 50g, but if it fits well I’ll order the 300 as well for the colder winter weather when it hits.
