Hello group!! My name is Bridgett and I have two dwarf female goats. They were bought about 4 months ago and the guys said he knew they were pregnant. So we have had them about four months and one day we think for sure they are pregnant and then like today we aren't sure? They have started to get pretty good bags on them and their nipples keep getting bigger and longer? Is there any way I can tell without taking them to the vet?
