Sheep can show and recognize emotion by facial expressions with other sheep. When they experience stress or isolation, they show signs of depression by hanging their heads and avoiding positive actions. Sheep make different vocalizations to communicate with one another.  The bleats of individual  sheep  are distinctive, enabling the  ewe  and her  lambs  to recognize each other's bleats . Each mother can recognize her lambs by their bleats alone. Sheep can amplify and pinpoint sound with their ears Sheep will communicate with their shepard especially when they are hungry and want their bottle or nuts.

Dog poop can cause fatal diseases in sheep. The poop on grazing land can pass worms and parasites to sheep. The eggs of worms and parasites can survive on the ground for a long time, so do not allow your dogs to poop in fields that do not currently have livestock grazing in them. Diseases transmitted to sheep through dog faeces can be fatal, and can cause unpleasant effects such as impaired vision and neurological symptoms.  There is compelling  evidence of the links between two specific diseases in livestock and the presence on grazing land of poop from infected dogs. Neosporosis can result in miscarriage in cattle and Sarcocystosis can be responsible for neurological disease and death in sheep. There is currently no licensed vaccines or drugs for these diseases.

Sheep have fantastic peripheral vision. Their  large, rectangular pupils  allow them to see almost 360 degrees. Sheep  can see behind themselves without turning their heads. Predatory animals that ambush their prey tend to have vertical slit pupils, while herbivores that are prey for other animals usually have horizontal pupils like the sheep. The sheep's eyes are key to keeping them alive. Sheep have poor depth perception which means they cannot see immediately in front of their noses. 

Sheep are intelligent loyal animals with superb memory and recognition skills. Scientific research has proven the brilliance of sheep. A study of sheep psychology has proven sheep can remember the faces of more than 50 other sheep for up to two years. They can recognize a familiar human face also. They may be nearly as good as people at distinguishing faces in a crowd.  Researchers say, "Sheep form individual friendships with one another, which may last for a few weeks. It's possible they may think about a face even when it's not there." The researchers also found female sheep had a definite opinion about what made a ram's face attractive. "Sheep showed clear behavioural signs of recognising… individuals by vocalising in response to their face pictures," says Kendrick. The team also found evidence that sheep can differentiate facial expressions, and prefer a smile to a frown. Keith Kendrick and his team at the Babraham Institute in Cambridg...
