Yesterday. He's quite picky with kibble and he (still) runs all over the place all day like a hyper maniac. He has always been quite thin (as opposed to fatty) and he was looking scrawny - so I added some stuff to his diet. I think his weight is okay - I feed him mostly Victor High Pro Plus and I use DYNE every other day along with BEYOND canned food. His weight picked up a bit and he currently looka like this.
