Um ... there's only one oxygen and all animals breathe it. The chemical formula is O2
Through their nose
No
Without lungs, pigs would not be able to breath air, and will die from asphyxiation.
Yes, but only if you hold your breath until then.
Probably lizards and flowers pigs, monkeys, baby breath , and lilies
the will pant and breath heavily. this is a sign that happens when it starts. they will also get bigger then they normally are.
Coffee pockets are made out of cow breath, grinded pigs feet and human toe nails
pigs noses are genetically modified so they can only breath through their noses, and can't smell anything. if a pig were to roll around in mud and eat muck and left overs they wouldn't notice the stench! so infact pigs have no clue what so ever that they smell. Ms Bilyad bioligy specialist
they should not breath heavily, this is a sign of phemonia and colds and/or a fever. if you can see your guinea pig breath heavily and can somtimes hear them smeaze or rattle or even breatyh in and out TAKE IT TO THE VET IMMEDIATLY! you guinea pig will die if not taken to the vet with these sympoms thank you
No but if your looking for a treat to give them nibble rings are good.
they breath through their nostrils like most other mammals. I dont think that they breathe through their mouths at all, but I could be wrong about that.
usually when a guinea pig dies its eyes are open, but if it died sleeping then its eyes should be closed.
