How to Tell If Your Dog Is Dilated?

Dilatation refers to the widening or enlargement of a body or structure. However, this term is not typically used in describing dogs or their physical well-being. There are various physical indications and symptoms through which dogs and pets in general communicate their health conditions and needs, but "dilatation" may not apply.

Could you describe more specifically what aspects of dog health concern you, and I'll do my best to provide relevant information within my abilities?
