There's a temptation, particularly with anything worn primarily for dog walks, to assume cheaper is more sensible, since it's just going to get muddy or covered in fur anyway. In practice, the opposite tends to be true, and nowhere is that clearer than with knitwear.
Cheaper knits, thinner yarns, looser construction, tend to pill quickly, lose their shape within a season, and stop providing much actual warmth fairly fast, particularly once they've been through a few washes. A dog walk in in practice cold weather exposes those weaknesses within weeks, not years, leaving you back at the shops sooner than you'd like.

Investment knitwear, properly spun wool, tighter construction, tends to hold its shape and warmth for years rather than months. It's the difference between a jumper that still looks and performs the same after fifty wears and one that's visibly tired after ten. Given how often a decent jumper actually gets worn for daily walks, that longevity matters more than almost any other consideration.
There's also the practical matter of how well a garment handles the specific demands of dog ownership. Fur, mud, the occasional damp patch from an over enthusiastic greeting, all of it needs to wash out cleanly without ruining the garment's shape or texture. Better quality wool tends to handle repeated washing considerably better than cheaper alternatives, which often shrink or distort after just a few cycles.
Cost per wear is the number that actually matters here, not the number on the price tag itself. A more expensive jumper worn for five years of daily walks works out considerably cheaper, in real terms, than a budget option replaced three or four times over the same period, aside from being noticeably warmer and more comfortable throughout.

There's also a comfort argument that's easy to overlook amid all the practical talk of durability and cost. Truly good wool simply feels different against the skin, softer, warmer, less itchy than cheaper synthetic blends. Given how many hours a week this garment actually gets worn, that comfort adds up to something worth paying for in its own right.
It's worth having at least two in rotation if budget allows, simply so one can be washed and rested while the other's in use. Wool benefits from a day or two of rest between wears to properly recover its shape, something a single jumper worn daily rarely gets the chance to do.
Storage matters too, more than people realise. Wool needs room to breathe between wears rather than being crushed into a drawer, and a proper fold rather than hanging on a hook helps a good jumper hold its shape for years rather than stretching out of true within a single season.
Beyond the practical case, there's something to be said for simply enjoying what you wear every day. Dog walks happen daily, rain or shine, for years. Wearing something really well made for that routine, rather than something purely disposable, changes how the whole habit feels, turning a twice daily obligation into something that's actually rather pleasant to put on.
