Puppy illness and aggression

many times with a thing like parvo - they DO get a ton of handling (gloved, but still) because the dogs need around the clock fluids, meds, etc.

The thing I've found with parvo dogs, after the illness is shed, that they mostly have a TON of pent up energy from being stuck in a 'sick ward'.

Socialize like crazy, get him out there as much as you can - I've never seen these issues resulting from parvo dogs - and I've dealth with my fair share!

Thanks for the response!

 Emma had parvo as a baby, and required hospitalization. She was also born at a shelter and lived her first 9 weeks in a kennel, so I don't think she really counts. She had some major behavioral issues that had to be worked through and still require management.

Your new baby is VERY cute!!! Congratulations!

 Get him in to a play group with socially appropriate dogs of all ages - better at a positive training center than at the dog park.  We advise this a lot with formerly sick pups, singletons, and those that left the litter too early.  Works wonders if you do it early, often and ongoing.  With the bullies, many centers limit their play to a certain age, usually 8-9 months, but take him till then, if that's the option, even if you must do it in class because they don't do play groups.  If you don't have access to a group, start your own on meetup.com.  Just make sure that all the dogs are fine with *unfamiliar* dogs.  Many owners think their dogs are social because they have another dog at home, or the dog plays with the neighbor's dog.  Then, they find that the dog wasn't socialized properly to others, and you don't want your pup to be the guinea pig for that.
