First day of school

[jaxdad]

Jax 15 wk male went to school for the first time last night puppy classes. He was the only one who started to growl at the other six dogs, he got put in time out three times in a rom within five minutes. Now I have had him around other dogs a pug(male) that was his age and they got along great once they knew each other and also my mothers dog a 5 yr mix female. But at school he was attacking everything big or small didn't matter what can I do to help him be more dog friendly in next class.

Jax was probably just a little overwhelmed

This is very common behaviour in puppies and generally by the last class they are playing nicely. Try to get him out and about a lot in 'safe' situations through the week.
