Not at all. Psyche doesn't even HAVE a collar, I don't think, and has maybe 2 harnesses. But I only ever use one. She never wears a collar, always the harness when we're out in public.
Crash had a collar... not sure where it is now... when I take him out, he wears one of Psyche's harnesses.
Simi has 3 collars. One is a "pretty" collar that will likely never fit her properly that I bought a year before she was even born. Another pink rolled leather collar I bought for 50% off that is too big for her, and then she has her Rogz collar, that I LOVE.
Just like this:
It's the best collar. Strong, secure and I can always easily find the ring to attach her leash. When I buy collars for all the dogs (because I feel like they should have at least one, lol) then they'll all be getting Rogz collars. They're not overly fancy, but I really like them.
But realistically, I'd rather spend my money on toys, treats, better foods, crates, etc., than collars, when collars are all either a)hidden by hair (Psyche, Crash, Zoey) or b) covered in mud 99.9% of the time (Simi).
