Canine Behavior/Return to obnoxious behavior


I have a 15 month old pit mix who was spayed last week. Since then she has been acting differently, allow me to explain. The first 10ish months she was the typical energetic, adorable yet ill behaved puppy. Almost overnight she turned into the perfect dog, no accidents, no chewing, calmer disposition. It was great.
Since her operation last week, she has returned to crazy amounts of energy, chewing, dumping garbage cans, and being obnoxious to get our attention.
Is this normal? Will it subside? And what can we do to help our dog who seems to be unmaturing?

I thought we were done with the puppy phase...

Find a more sophisticated veterinarian.  If your bitch was spayed with a high estrogen titer (before first cycle), she is "stuck".  She will require hormonal therapy for a while.  Every bitch should be allowed one full estrus cycle (and they can be "silent" so owners need to pay attention.)  The increase in risk of mammary cancer is small (less than 1%).  Most veterinarians still appear to be pushing spay before first cycle, a huge mistake, you can see the results.  A course of Progesterone treatment might be just the ticket for your dog.

Call the teaching hospital in your area and look for a veterinary internist (who will most likely require a referral from your vet) or a Veterinary Behaviorist (who might not).  Once you have your opinion, use followup feature (So I can see original question and answer) and we will use the medication as an opportunity to counter condition her present behavior.  Thank you.

I have spent my entire professional life rehabilitating the behavior of the domestic dog and I can answer any question regarding any behavior problem in any breed dog. I have answered more than 5,000 QUESTIONS on this site in the past (almost) eight years. If you are a caring, committed owner and need advice, I'm here for you. I am personally acquainted with my colleagues (Turid Rugaas, Ian Dunbar, etc.) who were members of an elite group in EGroups that I founded: K9Shrinks. THERE ARE NO QUICK FIXES for serious behavioral issues; not only is it unprofessional to offer same, it is also unethical. IF I ASK YOU SUBSEQUENT QUESTIONS, I NEED YOU TO INTERACT WITH ME. More information equals more credible answers and a more successful outcome. If you want ANSWERS THAT WORK, participate in any way I request. I'm quite committed to working on this site for YOUR benefit and the benefit of YOUR DOG. Help me in any way you can.
