I think we should try a harness on Susie - currently 3 1/2 months and weighing 32 lbs. A search on Amazon finds a few but can't see anything suitable for a dog this size with scope for growth. I know I may need a larger one in due course (though hope by then she will be as good as gold and walk nicely to heel!) and just need a collar. Any suggestions please re make, etc. (UK sources).
I onky recommend Perfect Fit https://www.dog-games-shop.co.uk/perfect-fit-fleece-dog-harness.html. as the harness comes in 3 separate ppieces it's possible to just change one part rather than the whole harness for growing pups. Also very helpful with enquiries
Like @Jojo83, I do like the perfect harness. Although for me I just started off with a light mesh harness from puppia until they were a bit older. I bought this one in Large for my then 3 month old puppy https://www.amazon.co.uk/gp/product/B003U057E6/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 Will see if I can dig out a photo of her wearing it
Huh - I really disliked the perfect fit harnesses. I found the straps very thin, the fleece didn't stay up the straps properly, and the amount of buckles was just something else - I really didn't want that many hard plastic bits on a harness. I bought my two perfect fits and gave them to a dog charity. I found them far too fussy and bothersome. The same company makes a fleece harness where the fleece is securely fastened to all the straps, without all the endless separate bits (and buckles and more buckles...which are not covered in fleece) which I've found easy to fit, and a great deal easier to use.
