Digital dermatitis appears as lesions which initially looks like raw, red, oval ulcer on the back of the heel. These lesions develop raised, hair-like projections or wart-like lesions, and some may extend up between the claws or appear on the front of the foot.

A scoring system was developed to classify the different stages of digital dermatitis, the M-stages system, where "M" stands for Mortellaro. The different stages are described as: M0, healthy skin; M1, early stage, skin defect < 2 cm diameter; M2, acute active ulcerative lesion; M3, healing stage, lesion covered with scab-like material; M4, chronic stage, that may be dyskeratotic (mostly thickened epithelium) or proliferative or both.

Diagnosis is principally based on history and clinical signs. It is very rare that attempts are made to isolate the bacteria.

Digital dermatitis is a disease that causes lameness in cattle. It was first discovered in Italy in 1974 by Cheli and Mortellaro. This disease is caused by a mixture of different bacteria. Anaerobic bacteria, including spirochetes of the genus "Treponema", are found in the lesions associated with the infection. Digital dermatitis is different from foot rot in cattle and both conditions may occur concurrently.

Digital dermatitis primarily affects dairy cattle and has been known to lower the quantity of milk produced, but the quality of the milk is unaffected.

Evidence show that risk factors favouring digital dermatitis outbreaks include: poor hygiene and high humidity; introduction of infected animals; no hoof care for heifers and dry cows; high levels of chronically infected animals; insufficient or inadequate hoof trimming; soft hooves and unbalanced nutrition.

Interdigital dermatitis appears as an infections of the skin between the claws and is usually very mild. There may be fluid or a scab in that area, and there is rarely lameness. There is then progression to the heels which become raw and cattle will experience pain. Chronic cases will show changes of the hoof including hyperplasia of the interdigital tissues and muscle atrophy in the affected limb. The horn may become underrun.

Diagnosis is principally based on history and clinical signs. It is very rare that attempts are made to isolate the bacteria.

Interdigital dermatitis in cattle is caused by the anaerobic bacterium "Dichelobacter nodosus". This is also the agent of footrot in sheep, but strains appear to be different and there is no cross-infection.

Interdigital dermatitis is different from footrot in cattle and both conditions may occur concurrently.

The condition most commonly occurs in farms with a high stocking density or where cattle traffic is high and is most prevalent in Winter.

The areas most affected are the toes, fingers, earlobes, nose.

- Blistering of affected area

- Burning and itching sensation in extremities

- Dermatitis in extremities

- Digital ulceration (severe cases only)

- Erythema (blanchable redness of the skin)

- Pain in affected area

- Skin discoloration, red to dark blue

Chilblains usually heal within 7–14 days.

Chilblains — also known as pernio, chill burns and perniosis — is a medical condition that occurs when a predisposed individual is exposed to cold and humidity, causing tissue damage. It is often confused with frostbite and trench foot. Damage to capillary beds in the skin causes redness, itching, inflammation, and sometimes blisters. Chilblains can be reduced by keeping the feet and hands warm in cold weather, and avoiding extreme temperature changes. Chilblains can be idiopathic (spontaneous and unrelated to another disease), but may also be a manifestation of another serious medical condition that must be investigated. A history of chilblains suggests a connective tissue disease (such as lupus). In infants, chilblains together with severe neurologic disease and unexplained fevers occurs in Aicardi–Goutières syndrome, a rare inherited condition.

Recurrent bouts of balanitis may cause scarring of the preputial orifice; the reduced elasticity may lead to pathologic phimosis.

Symptoms can include:

- First signs – small red erosions on the glans

- Redness of the foreskin

- Redness of the penis

- Other rashes on the head of the penis

- Foul smelling discharge

- Painful foreskin and penis

Viral arthritis is an infectious condition in chickens and to a lesser extent, turkeys, due to a reovirus.

The disease is egg-transmitted.

The prominent symptom is a swelling of digital flexor and metatarsal extensor tendons. The hock joint itself is not so sharply affected, showing just a small amount of synovial exsudate when opened.

Infectious bovine keratoconjunctivitis, or IBK, is a veterinary infection of cattle caused by "Moraxella bovis", a Gram-negative, β-haemolytic, aerobic, rod-shaped bacterium. It is spread by direct contact or by flies serving as vectors. It is the most common ocular disease of cattle (mostly beef). IBK is similar to human pink eye and causes severe infection of the conjunctiva, edema, corneal opacity, and ulceration. This disease is highly contagious and occurs worldwide. Younger animals are more susceptible, but recovery with minimal damage is usual, if they are treated early. The disease is also known as pinkeye, New Forest eye or blight.

The bacteria invade the lacrimal glands of the eye, causing keratitis, uveitis, and corneal ulceration. Cattle show signs of pain, increased lacrimation, excessive blinking, and conjunctivitis. More severe cases may show systemic signs such as anorexia and weight loss. Chronic untreated cases can become blind. Diagnosis is usually based on the clinical signs, but the bacteria can be cultured from lacrimal swabs, or visualised on smears of lacrimal secretions.

Acral fibrokeratoma (also known as an "Acquired digital fibrokeratoma," and "Acquired periungual fibrokeratoma") is a skin lesion characterized by a pinkish, hyperkeratotic, hornlike projection occurring on a finger, toe, or palm.

BRD often develops within 4 weeks of cattle transport. The biggest sign of the pneumonia that BRD causes is depression, shown as droopy ears, dull eyes, and social isolation. Additionally, most cows will have a fever above . Other symptoms include coughing, decreased appetite, and breathing difficulty.

Typically, Dupuytren's contracture first presents as a thickening or nodule in the palm, which initially can be with or without pain. Later in the disease process, there is painless increasing loss of range of motion of the affected fingers. The earliest sign of a contracture is a triangular “puckering” of the skin of the palm as it passes over the flexor tendon just before the flexor crease of the finger, at the metacarpophalangeal (MCP) joint. Generally, the cords or contractures are painless, but, rarely, tenosynovitis can occur and produce pain. The most common finger to be affected is the ring finger; the thumb and index finger are much less often affected. The disease begins in the palm and moves towards the fingers, with the metacarpophalangeal (MCP) joints affected before the proximal interphalangeal (PIP) joints.

In Dupuytren's contracture, the palmar fascia within the hand becomes abnormally thick, which can cause the fingers to curl and can impair finger function. The main function of the palmar fascia is to increase grip strength; thus, over time, Dupuytren's contracture decreases a person's ability to hold objects. People may report pain, aching and itching with the contractions. Normally, the palmar fascia consists of collagen type I, but in Dupuytren sufferers, the collagen changes to collagen type III, which is significantly thicker than collagen type I.

Odonto–tricho-ungual–digital–palmar syndrome is an autosomal dominant skin condition with salient clinical features of natal teeth, trichodystrophy, prominent interdigital folds, simian-like hands with transverse palmar creases, and ungual digital dystrophy.

People with severe involvement often show lumps on the back of their finger joints (called “Garrod's pads”, “knuckle pads”, or “dorsal Dupuytren nodules”) and lumps in the arch of the feet (plantar fibromatosis or Ledderhose disease). In severe cases, the area where the palm meets the wrist may develop lumps. Severe Dupuytren disease may also be associated with frozen shoulder (adhesive capsulitis of shoulder), Peyronie's disease of the penis, increased risk of several types of cancer, and risk of early death, but more research is needed to clarify these relationships.

Because of the number of possible viral/bacterial precursors to BRD, there are a number of treatment options circling around the three main aggravators of the disease: Viruses, Bacteria, and Stress.

A Myxoid cyst (also known as a "Digital mucous cyst," and "Mucous cyst") is a cutaneous condition often characterized by nail plate depression and grooves.

Paravaccinia virus presents itself with blisters, nodules, or lesions about 4 mm in diameter, typically in the area that has made contact with livestock that is infected with bovine papular stomatitis. Lesions may begin forming as late as three weeks after contact has been made with an infected animal. In rare cases, lesions may be seen systemic. General signs of infection are also common, such as fever and fatigue.

Infected livestock may present with blisters or lesions on their udders or snout. Often, however, infected livestock show little to no symptoms.

Runner's toe is a common condition seen in runners caused by downward pressure or horizontal separation of nail plate from the nail bed. This repetitive traumatic injury leads to bleeding and pooling of blood underneath the nail plate. Clinically, it is characterized by reddish-black discoloration of the toe nail. The nail plate may also become thicker and more brittle as a result of the injury (onychochauxis). Fortunately, the deformed nail plate will gradually grow out and be replaced by new, normal-appearing nail plate in several months time. Infrequently, the toe may become painful and require surgical drainage.

Runner's toe is often associated with malfitting shoes and insufficient space for the toes. Some susceptible runners may also have Morton's toe. In this variant of human foot anatomy, the second toe extends further out than the great toe. The key to prevention of runner's toe is to purchase properly fitted shoes.

The condition also results from a traumatic injury, such as slamming a finger in a door, or from sports activities, such as climbing or hiking rugged terrain. A subungual hematoma that results from the repetitive thrusting of the longest toe into a shoe's toe box is called jogger's toe or runner's toe.

The bleeding comes from the (vascular) nail bed underlying the (avascular) nail plate. A laceration of the nail bed causes bleeding into the constricted area underneath the hard nail plate. Throbbing pain is common. The nail develops a black discoloration overlying the nail bed but under the nail plate.

A subungual hematoma is a collection of blood (hematoma) underneath a toenail or fingernail (black toenail). It can be extremely painful for an injury of its size, although otherwise it is not a serious medical condition.

Presents as a sensation of food getting stuck (dysphagia) in the mid- or lower esophagus, atypical chest pain, or cough. Patients often state they must drink liquids to swallow solid food. This motility problem results from atrophy of the gastrointestinal tract wall smooth muscle. This change may occur with or without pathologic evidence of significant tissue fibrosis.

Raynaud's phenomenon is frequently the first manifestation of CREST/lcSSc, preceding other symptoms by years. Stress and cold temperature induce an exaggerated vasoconstriction of the small arteries, arterioles, and thermoregulatory vessels of the skin of the digits. Clinically this manifests as a white-blue-red transitions in skin color. Underlying this transition is pallor and cyanosis of the digits, followed by a reactive hyperemia as they rewarm. When extreme and frequent, this phenomenon can lead to digital ulcerations, gangrene, or amputation.

Ulceration can predispose to chronic infections of the involved site.

The most common form of the disease is the head and eye form. Typical symptoms of this form include fever, depression, discharge from the eyes and nose, lesions of the buccal cavity and muzzle, swelling of the lymph nodes, opacity of the corneas leading to blindness, inappetance and diarrhea. Some animals have neurologic signs, such as ataxia, nystagmus, and head pressing. Peracute, alimentary and cutaneous clinical disease patterns have also been described. Death usually occurs within ten days. The mortality rate in symptomatic animals is 90 to 100 percent. Treatment is supportive only.

Diagnosis of paravaccinia virus will often come from Polymerase chain reaction screening ordered by their physician. However, due to how common paravaccinia virus is in rural areas, individuals typically do not seek professional help in diagnosis. Instead individuals may refer to people with local knowledge of the cattle in their area such as ranchers, or veterinarians who have some familiarity with the infections in the region.
