Hi!

Please double-check the gender of your piggies and also check for signs of skin parasites. Mis-sexing is unfortunately not at all uncommon.

If you have two sows and not a boar and a sow, then please read up on the guides below; you will hopefully find them very helpful.
The growling is called rumbling or rumblestrutting (in combination with the attendant body language).
