**I need advice about a female puppy’s behavior problem.**

A female puppy has been living with us since she was one month old. She lives with an older male dog (12 years old). The intention was for them to potentially mate in the future, although they are different breeds.

As the puppy grew, her behavior gradually became more difficult. She received her vaccination at around 7 months old, and unfortunately, she was taken outside for socialization quite late.

Based on my observations and my relationship with the current owner, I am trying to help reduce her behavioral problems. I am not the owner of the dogs, but the owner asked me for help.

The puppy is very intelligent and confident. She shows strong food guarding behavior. If someone enters her space while she has food or something valuable, she may rush toward them, bark, and attack in order to scare them away and make them leave.

However, when we take both dogs outside for walks, she is extremely affectionate. She becomes excited, licks the person who takes them out, and shows a loving personality.

With strangers, if someone approaches her, she may bark, make warning sounds, and act as if she is trying to protect herself or her territory.

There is also a possibility that she is pregnant, and recently her behavior has become more dominant. She seems to have a stronger personality than the male dog and often behaves like the “alpha” of the household.

My questions are:

1. Is this behavior related to lack of early socialization, hormones, pregnancy, fear, or resource guarding?
2. How can we reduce her food aggression and protective behavior safely?
3. What training methods would you recommend for a very intelligent but dominant female dog?
4. Should we consult a veterinary behaviorist or trainer?

I would appreciate any professional guidance and a step-by-step approach to improve her behavior.

Sorry to see you're dealing with a difficult situation. Do you know if she turned out to be bred? Unfortunately, this type of situation requires a lot of details of the dogs environment and potentially video evidence of described behaviors. I see this is for another owner's dog, so this may be difficult to assess. Positive reinforcement is the mainstay for correcting behaviors and consulting veterinarians and behaviorists is never a bad idea.
