post neuter aggression?

If his neuter is recent (is it?) then he may still be sore or feeling vulnerable and that could definitely be a transient issue. Hormones are outta whack for MONTHS following a s/n (especially a late in life s/n)and the dogs behavior at that time should not really be considered to be permanent UNLESS it is reinforced. Allow the dog to be at home...and in a comfortable environment. Keep stress minimal and exercise in a smart way...busy the mind AND body.

If this neuter was like 6months ago or longer on then I would worry but IMO it is WAY too early to consider this anything but some major hormonal turmoil coupled with the trauma of being placed in a series of new situations...a general lack of trust or acceptance of the permanence of this situation, etc...Perfect Storm as it were.

I have seen data like you speak of but it was mainly geared towards bitches...not dogs.

Thanks, Gina. I 'think' the neuter was in September.

that is what I told her this morning after finding out it began immediately after the removal of pain meds from the neuter

From what I recall this dog was a stray for a bit before finding you and you rescuing him? If that is the case he may have, in his mind VERY good reasons to resent other dogs (competition) in his space. He may NEVER like other dogs in his space or around at all. Add in that there may be Chow...which aren't reknowned for their social skills LOL..and well...his new home may need to accept that some dogs...NEVER like other dogs. Nor do they have to to be "normal" IME.

 that's the one

again agreed - although apparently he did get along with some and really he was fine with my dumb-butt except when spazzy was too in his face trying to get him to play.  This dog would love to just lay around in the sun somewhere day in and day out.  She said if he got any more relaxed at home he'd not move at all.

I think I mentioned to her that he would be great for an older couple that didn't want anything much from the dog - other than it be around to receive petting 

I don't really have any advice, just wanted to say that Bailey was VERY cranky (especially towards other dogs) for a while after he was neutered. Maybe it's just a hormonal thing?

 I missed her seminar in MA but I chatted with her at the McConnell seminar - Parvene Farhoody has done some research on neutering and aggression.  Her work suggests that aggression can increase post neuter.  Fascinating stuff - you may want to see if she's presenting anywhere near you.

Apollo was NEVER leash reactive until he was neutered. He was neutered later in life (3-5yrs old), and him being leash reactive lasted for almost 2 years (not just until he was healed, actually he wasn't leash reactive until he was healed). We trained and conditioned and worked, and now he isn't leash reactive but only because his obedience over rides it, I believe.

 Thanks Ann & Steph I am passing the info posted here on to the foster/owner

 I have known quite a few boy dogs who become reactive or less tolerant of other dogs once they were neutered.
