Why has my dog suddenly started chasing our cats?

Hi there!

We have a 3 year old pooch who has been so lovely with our two cats, and if anything has been scared of one of them who tends to bully him. We recently got a puppy who is also very good with cats, however now all of a sudden the older dog has “noticed” them and is starting to chase them and at times corners them with a play bow, being kind of pushy in trying to engage them. We trust that he won’t hurt them intentionally but are kind of perplexed at the sudden emergence of this behavior, and don’t want out cats to get stressed. Clearly it has to do with the puppy coming, but what about that has changed things for him? Is he trying to show off? Does the puppy excite in him some innate pack like mentality causing his prey instinct to surface more? Is he just generally really excited and trying to play with anything that moves? Is there any way to work on this or should it just pass?

Any advice would be greatly appreciated, thank you!
