I think we can't generalize advice - what is good for one dog is not always good for another.
My dog is not 1 lb but he is under 4 and my vet told me to not put him under for neutering or to remove crowded teeth (unless they start bothering him) because the anaesthetic risks are higher for dogs under 4 pounds.
That seems like sound advice to me in my situation. However, I certainly wouldn't say that spaying/neutering is wrong for ALL dogs or right for ALL dogs and I wouldn't say that vets or breeders are the best for advice as they all have agendas despite good intentions.
So, just use some common sense. I think one cannot research enough with respect to possible side effects of any surgery - that is just being responsible.
At the same time, it's not wise to generalize anything as situations are specific to those involved. |
