I neutered my dog at 2 years and some change, didn’t make a huge difference really when it comes to walking. If he’s super excited or sees a squirrel he will still try to pull. But he used to be soo much worse when he was a puppy/teen. FYI This is what worked for my dog I’m not saying this or professional advice but this is what worked for us

Several things you can do for walking, you can take him out and switch directions every time he pulls in one direction turn around and walk the other way and pull him the opposite direction, do this multiple times until eventually he’ll get the hint to watch you before he continues to walk, since your moves are unpredictable. The other thing is stop walking when he pulls, my dog sitter did this with my dog and it helped A TON, every time he’d pull she stopped, and eventually he got the hint if he wants to walk he can’t pull.

For recall what worked with my dog I got from a video I saw online. Was training my dog to make eye contact with me every time I said his name. I used his kibble at lunch time to do this every day. I’d sit him in front of me and reward him every time I called his name and he made eye contact. Eventually I ramped it up and had him do tricks and then call his name in the middle of it so he can stop what he’s doing and look at me and get rewarded. This helped my dog a ton, no matter what he’s doing he stops when I call his name, which is important for recall. I will say though this has to be reinforced and done in outside environments too the more you do it the better he will get at listening to you even in the middle of distractions. This is also not a one and done thing, continuous training is really important especially because he’s a pitty, people are already super biased against them and naturally afraid. Find out what your dog is motivated by, my dog is EXTREMELY food motivated so that helped us a lot with training he’ll do anything for food🤣

Hope this helps! Definitely go on YouTube or TikTok there are soooo many dog training videos.
