Dogs can detect a change in movement that exists in a single diopter of space within their eye. Humans, by comparison, require a change of between 10 and 20 diopters to detect movement. [36] A test has estimated poodles' visual acuity to have a Snellen rating of 20/75, a relatively low score compared to humans' vision. [28]
As in dogs, tumor size is an important prognostic factor, although for tumors less than three centimeters the individual size is less predictive. According to one study, cats with tumors less than three cm had an average survival time of 21 months, and cats with tumors greater than three cm had an average survival of 12 months. [ 17 ]
The cephalic index of a vertebrate is the ratio between the width (side to side) and length (front to back) of its cranium (skull). This ratio does not concern the muzzle or face, and thus is distinct from the craniofacial ratio , which compares the size of the cranium to the length of the muzzle.

[1] Mast cell tumors are the most common type of skin cancer in canines. [1] Lymphoma; Prostate cancer; Brain cancer; Hemangiosarcoma is a type of cancer that is ...
Particularly on the limbs, these basic tumor surgery rules cannot always be fully implemented because this would result in the loss of nerves, vessels and tendons, so that amputation must also be considered. In some circumstances, the use of H₁- and H₂-receptor antagonists prior to surgery may attempt to reduce tumor size. The ...
An endocrinologist is only involved in preparation for an endoscopic endonasal surgery, if the tumor is located on the pituitary gland. The tumor is first treated pharmacologically in two ways: controlling the levels of hormones that the pituitary gland secretes and reducing the size of the tumor. If this approach does not work, the patient is ...
Overweight female dogs are especially prone to developing these tumors, and most older or overweight dogs have at least one lipoma. [46] [47] In dogs, lipomas usually occur in the trunk or upper limbs. [45] They are also found less commonly in cattle and horses, and rarely in cats and pigs.

Veterinary surgery is surgery performed on non-human animals by veterinarians, whereby the procedures fall into three broad categories: orthopaedics (bones, joints, muscles), soft tissue surgery (skin, body cavities, cardiovascular system ...
