Inability To Urinate After Surgery

I recently neutralized by pit bull, Rufio, who was 2 in February. It was established a little over a month. The surgery was in early March. I feared that having fixed after two years could change his personality and it seems that my fears were correct. It is a pit bull love that is devoted to his master (me) and never showed signs of aggression after the surgery, so try not to be biased because the pit bull stereotype wrong. The only thing I have noticed since surgery is the apparent inability to reproduce (which was needed as it spends time playing with a dog unfixed female).

Since the surgery, Rufio has been more aggressive (ie, pinching / slot for people they know or just met in a friendly, violent barking at strangers who pass the parked car, etc.), where as it was before aggressive scenarios appropriate (ie possibility of an intruder, or to protect my safety / fear that I might be in danger, etc..)
In addition, he has been urinating in the houses into which they are familiar - no new territories! It is certainly pot and trained as a puppy, he trained very quickly pot so I'm not sure what is happening here. It's almost as if he had stepped back in his training.

There were a few other cases in which Rufio showed strange ways or actions which do not correspond to his personality, and everything started after surgery. Does anyone know what happens? Has anyone heard of something similar to this place before? Please help! I am in fear of having to abandon him if he does not begin to act like he used to. I feel like he had a lobotomy!

You seem intelligent and you have expressed your concern in a manner that requires a correct answer.
Neutering a dog does come with a host of problems that people here will not talk to you because castration and neutral police are trying to get everyone to remove all the reproductive organs of their dogs.
Other then the ability to breed, dogs do have problems because of the lack of hormones that were present before.

In humans, there HRT. Among men, we can obtain exogenous testosterone in a patch, cream, injection, etc. .. women they can get into oestrogens in the same way, have you ever thought why?
Men with LOW testostrerone are more irritable and more aggressive with men with high levels of the hormone.
Women who have undergone a complete hysterectomy may be very difficult to live, believe me, I saw several!

Are we naive enough to think that the deletion of these hormones in an animal will have no effect on his system?
I have never in 30 years fixed any dog that I owned and I've never been pregnant, I am not a breeder and I do not want to be one.
Did you know that in most progressive countries in Europe "fixing" your dog is against the law unless there is a good medical reason behind it.

The issues you describe may or may not go, my opinion is that they will not if they are hormone dependent.
Hope I helped.

Have you expressed your concerns with your veterinarian?

Sterilization is an abrupt change for the dogs, most of the time they are in pain, have a hormonal imbalance, and it takes time for them to get back to where they were. You have to keep him training, he should not be treated differently now, he needs to be disciplined and trained the summer he was when he was in-touch.

Find a behaviorist, after talking to your veterinarian and have your dog evaluated.

wait for it to heel completely. All my dogs seem to calm down after being fixed.

My mother, finally, after 3 years of begging me to leave my own pit bull, and once we set it has become aggressive, but the SAI veterinarian.
