We've taken on a 10 month old poodle mix Early days and still getting to know each other but going well except for separation anxiety - he is a rehome rather than rescue so came from a loving home but zero training and NEVER been left alone or at night. He's not castrated and I'm unsure whether we should get it done. Vet said leave it a month or so until he's fully settled, there are some health benefits when older but it's not essential unless he's a pain around in-season dogs (not sure how I'd know?!) or aggressive which he's not albeit a bit bitey/mouthy when people arrive but think that's lack of training rather than aggression. Slightly concerned the process of having an op and being away from us could make his SA worse or is it true it can settle highly strung dogs?
Any pearls of wisdom gratefully received.
