Second-hand steelies from a scrapyard in the right bolt pattern are often under fifty dollars a set. Check the centre bore and offset before you get excited.

I stopped buying online entirely for anything I haven't already run in. A sale price on a shoe I can't run in is not a saving, it's a slower way of wasting money.

Whatever you buy: no metal utensils, and no thermal shock. Cold water into a hot enamelled pot is how most of the chipping stories in this room begin.

Switched both of mine to save money and switched one back. The younger one was completely unbothered. The older one had loose stools for about three weeks, which everybody told me was a too-fast transition, except I took two weeks over it. Some dogs are just sensitive to a fat and fibre profile change, and no amount of slow transition fixes that. Budget for the possibility that it works for one animal and not the other.

Body weight affects how far a given dose moves the number. That's a conversation for your doctor rather than for us, but it's a legitimate reason two people on identical doses land in different places, and worth raising with them instead of assuming the supplement failed.
