The excellent fit and thoughtful design of the Tre Ponti harnesses give maximum movement freedom to the dog. Both the ergonomic design and the fit are adapted to the size of the dog.
The Fibbia has a buckle closing. This classic Fibbia model is not adjustable, so a lot of dogs will be in between 2 sizes.
That is why Tre Ponti developped the Adjustable Fibbia, which can be adjusted at the girth, available in different colors and styles
Sizes Fibbia harnasses according to an average weight indication: 1 - up to 3 kg 1,5 - up to 4 kg 2 - up to 5 kg 2,5 - up to 6 kg 3 - up to 7 kg
Don't fix the buckle all the way at the bottom, because then there will be too much pressure on the closure/buckle. For the same reason it is best not to apply this method to sizes larger than size 3.
PHILOSOPHY of TRE PONTI Tre Ponti harnesses are all designed from the idea to give the dog the best possible freedom of movement. Tre Ponti harnesses never touch negative pressure points. Tre Ponti has chosen not to develop one type of harness for all the dogs that would needed to be adjusted for different sizes or types of dogs. No, it is a deliberat choise to design different models for different sized dogs, because they have specific needs. This creates the optimum gear for any size dog.
