So, we went to our local pet shop to try out some harnesses. We tried a trixie and a padded Y shaped harness (a perfect fit look alike?) but didn't feel they fitted that great. They also do the proper perfect fit but they looked quite chunky. As did the Julius range.
We had this harness at home, just from Pets at Home, so gave it a go but I'm not sure it is far enough out from Lilly's armpits. But much further and it may rub on her lumpy bit. As indicated


The depth of her chest is 72cm at the widest point which is just in front of her lump.
This harness measures 14cm from the back of the collar piece and 24cm underneath from the front ring (middle of the Y).
Any thoughts on whether this harness is good/bad/indifferent fit wise for occasional use, or if another model might be better from your experiences.
Finding it hard to assess given the lump is getting quite prominent (PS vet thinks it is just a fatty lump and we aren't at this point planning on having it removed)
Thanks.
