Single, traumatic experiences or repeated exposure to frightening stimuli can cause reactions ranging from mild fear to extreme phobias. The onset of noise sensitivity may occur during different developmental or life stages. Medical conditions such as pain (i.e., ear infection or arthritis) have been associated with noise sensitivity in dogs. Dogs that experience extreme fear and/or phobic behaviors need professional intervention. The first step is to schedule an appointment with your veterinarian.

Dogs may become frightened of specific locations due to a traumatic event or negative experience that occurred at the location. Comfortable exposures during a puppy's sensitive socialization period may prevent fear from developing. Treatment includes behavior modification and medication, in some cases.

A dog may develop a fear-based response toward people or other animals for a number of reasons, including inadequate socialization, emotional trauma, genetic predisposition, or an underlying medical condition. Dogs indicate fear by using postures such as stiffening, cowering, or moving away. If the trigger remains too close for comfort, a fearful dog can exhibit an aggressive response such as a growl or snap. Dogs that experience intense fear benefit from professional intervention.

Fear can be a normal response to a threat, but it can also be maladaptive, contributing to emotional and physical distress. Anxiety is the anticipation of fear and can contribute to chronic stress and behavioral illness. Phobias are intense fear responses to relatively benign triggers. Behavior modification and, in some cases, medications may be used to treat fear, anxiety, and phobias in dogs and cats.

A feather cyst is a malformation of a feather follicle whereby the feather(s) do not exit the skin, and instead become buried in a cyst under the skin. They can become quite large and be painful to the pet. These cysts require veterinary attention and if injured, may bleed extensively.

Feather loss occurs either because the bird is truly losing feathers or because the bird, or its cage-mate, is picking out its feathers. Feather Destructive Behavior (FDB) is a general classification that describes the many types of damage a bird can do to its own feathers, including feather picking. Feather loss and feather-picking can also be caused by diseases that result in irritation or pain for the bird, or damage to, or inappropriate growth of feathers. Feather loss and feather-picking are complicated problems. For specific advice, your bird should have a thorough work-up by a veterinarian familiar with birds.

A fecal Baermann is a special fecal test used to diagnose infection by parasites that pass larvae in stool instead of eggs. A small golf-ball sized sample of fresh stool is mixed with warm water to encourage larvae to separate from the fecal material to allow identification. The most common parasite diagnosed with a fecal Baermann is lungworm, which typically causes signs of coughing.
-
A fecal flotation is a screening test for internal parasites. It is performed by mixing a small sample of stool with a special solution that causes any parasite eggs to float to the surface of the solution. Young pets need multiple fecal flotations to screen for infection, while adults may only need a fecal screening once yearly unless they are at higher risk of infection.
-
A fecal occult blood test screens for the presence of hemoglobin (a component of red blood cells) in a fecal sample. Many conditions can cause blood to appear in the stool including intestinal ulceration, neoplasia, dental disease, and parasites.

Fechavirus is a type of parvovirus. It is a newly discovered gastrointestinal virus identified in cats in 2018. The significance of fechavirus in pet cats is unknown at this point. The most common signs associated with fechavirus are diarrhea and vomiting. If your veterinarian suspects fechavirus, your cat will receive supportive care to control clinical signs and prevent dehydration.
