I need to no if my other puppy and dog can catch parvo from my sick puppy please help me.

Are they current on vaccinations? Yes they can. And it can be deadly if not treated immediately. Get your puppy to a vet!

Only a vet can treat parvo, like Mamaof2boys stated.

The other two dogs are at risk, especially the other puppy.

Even if they're current on their vaccines they can still get parvo, but a dog that's had all its shots, and is current on its yearly vaccination, will be safer, or get a milder form of parvo.

How old are the other two dogs? Have they had all of their shots?

Just curious, what is skixz disease. Is this a weird keystroke on a mobile device?

Yes it is highly contagious and the vet is the only one with the proper treatment needed.vet asap!!
