How can I make a command that makes all my wolves sit and stand?

I've started a new Minecraft world and decided that I wanted to reach functional invulnerability by having like 50 unnamed wolves follow me around. However, this comes with a few issues, because having them follow around all the time makes it impossible to loot desert temples, they die by the dozen whenever I jump into a ravine, etc. It is a hassle to make them all sit and stand up, so I tried making a command that makes them all sit.

Here's what I tried so far:

Now the key to this seems to be the /data command. The command:

/data merge entity @e[name=JackLondon,limit=1] {Sitting:1}

allows me to make JackLondon the wolf sit, which is great.

The issue is that the /data command does not readily work with more than one entity at a time and I haven't found a way to circumvent that. I also haven't found a way to make it affect multiple unnamed entities.

Any code that allows me to make wolves or pets in general sit and stand all at once would be welcome.

You can use /execute to make every wolf execute the /data command and modify its own NBT data:

/execute as @e[type=wolf] run data merge entity @s {Sitting:1b}
