My 10 week old puppy mix. Is very aggressively fighting with my Chihuahua

[Karen]

I have him in training only second class today. He does wonderful there will sit,lay down, stay for 20 seconds and walk on leash. Unfortunately he starts playing and as soon as he got the upper hand on a dog at least twice his size he got aggressive again. When I fed him dinner tonight I was stepping between him and his dish to show him I’m the alpha first time fine second time bit me. Swatted his butt ha backed off. I made him sit at my feet until he has calmly waiting then I gave him his food back and waited for him to finish. Is this correct thing to do?

Yes, making him wait until after the other dog has eaten in a good thing.

I would talk to your trainer, and also Google "Nothing In Life is Free" training for dogs. Figure out his motivation, and limit any playtime with other dogs right now - as soon as he shows sign of getting overexcited, call him back to you, have him run through his tricks, etc., to distract and calm him.

When I say figure his motivation - is he food focussed, or toy focused/ What, besides positive attention and praise, is his favorite reward?

Oh! I have a Chihuahua too. I don't usually show it to other large dogs because I'm scared of what will happen.
