Cavalier King Charles Spaniel with bandaged foot A dog's injured leg. The health of dogs is a well studied area in veterinary medicine.. Dog health is viewed holistically; it encompasses many different aspects, including disease processes, genetics, and nutritional health, for example.
[35]: 140 The dog's visual system has evolved to aid in hunting. [28] Dogs have been shown to be able to discriminate between humans (e.g., identifying their human guardian) at a range of between 800 and 900 metres (2,600 and 3,000 ft); however, this range decreases to 500–600 metres (1,600–2,000 ft) if the object is stationary.

Phenylbutazone, often referred to as "bute", [1] is a nonsteroidal anti-inflammatory drug (NSAID) for the short-term treatment of pain and fever in animals.. In the United States and United Kingdom, it is no longer approved for human use (except in the United Kingdom for ankylosing spondylitis), as it can cause severe adverse effects such as suppression of white blood cell production and ...
A Galapagos shark hooked by a fishing boat. Pain negatively affects the health and welfare of animals. [1] " Pain" is defined by the International Association for the Study of Pain as "an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage."
[137] [138] [139] Specialists believe that all vertebrates can feel pain, and that certain invertebrates, like the octopus, may also. [137] [140] [141] The presence of pain in animals is unknown, but can be inferred through physical and behavioral reactions, [142] such as paw withdrawal from various noxious mechanical stimuli in rodents.

In dogs signs of primary pulmonary disease include a cough, fever, weight loss, anorexia, and lethargy. Disseminated disease occurs when the fungus has spread outside of the lungs and may include clinical signs such as lameness, pain, seizures, anterior uveitis, and localized swelling. [17]
A dog may misuse its rear legs, or adapt its gait, to compensate for pain in the forelimbs, notably osteoarthritis, osteochondritis (OCD) or shoulder or elbow dysplasia, as well as pain in the hocks and stifles or spinal issues. It is important to rule out other joint and bodily issues before concluding that only hip dysplasia is present.
Invertebrate nervous systems are very unlike those of vertebrates and this dissimilarity has sometimes been used to reject the possibility of a pain experience in invertebrates. In humans, the neocortex of the brain has a central role in pain and it has been argued that any species lacking this structure will therefore be incapable of feeling ...
