Struggling with my adopted dog's behavior

It is common for dogs to still be crazy and not "trained" at 1 year. Dogs are still developing and don't start to slow down emotionally and hyperactivity wise until 2 years or later depending on the breed. I would suggest to continue to work on training more and to work with trainers that are experienced with the breed/mix that you have as well as the specific behavioral issues that you are concerned with. If you can't afford training you could reach out to a local rescue and tell them you're interested in getting help with training for your dog and see if they have any trainers that might be willing to help for free so the dog doesn't become at risk of needing to be rehomed later down the road. A lot of times rescues would rather you reach out and ask for help before it gets to the point that you need to rehome a dog, so ask around and look into some organizations! Ps- I adopted a dog and was not able to provide them enough training and had a lot of regrets when they later became aggressive towards my other dog. I ended up having to give the dog back after having her for 1 year after becoming dangerous and unmanageable, so I get what it feels like to wonder if you had more time and had given them more training, etc. I think despite not being perfectly trained and having behavior issues, you could still claim that yojr dog has had a happy and safe life in a loving home, and that's what counts. A lot of dogs don't even get to experience that, and it's always better than being in a shelter or ending up in an abusive home. Those are somethings I think about when I feel upset and am hard on myself. Anyway I'm here to talk if you need to!

Be very careful if you give him away, do not give him away for free, many dog fighting rings get their dogs that way. I think if you keep at the training consistently along with enlightenment training he may start to show some progress, but it has to be consistent. Dogs getting protective over their food is super common and natural, just feed your dog alone, in a crate if he has one. Crates are great for creating a safe space for your pup.
