Hemangiosarcoma is a rapidly growing, highly invasive variety of cancer that occurs almost exclusively in dogs, and only rarely in cats, horses, mice, [1] or humans (vinyl chloride toxicity). It is a sarcoma arising from the lining of blood vessels; that is, blood-filled channels and spaces are commonly observed microscopically. A frequent ...
Thaiwong et al. [6] submitted a publication in 2016 on a dual infection incident of CaCV and canine parvovirus in a breeding colony of dogs. Two disease outbreaks occurred in Michigan in 2013 and 2014 in which a group of related Papillon dogs became ill and some died shortly (within 1 week) after symptoms began to show.
A dog displaying a typical clinical picture of visceral leishmaniasis. Canine leishmaniasis (LEESH-ma-NIGH-ah-sis) is a zoonotic disease (see human leishmaniasis) caused by Leishmania parasites transmitted by the bite of an infected phlebotomine sandfly. There have been no documented cases of leishmaniasis transmission from dogs to humans.
The narrowing of blood vessels leads to an increase in peripheral resistance, thereby elevating blood pressure. While vasoconstriction is a normal and essential regulatory mechanism for maintaining blood pressure and redistributing blood flow during various physiological processes, its dysregulation can contribute to pathological conditions.
Internal bleeding (also called internal haemorrhage) is a loss of blood from a blood vessel that collects inside the body, and is not usually visible from the outside. [1] It can be a serious medical emergency but the extent of severity depends on bleeding rate and location of the bleeding (e.g. head, torso, extremities).
Symptoms include crying, weakness, depression, discharge from the nose, soft, yellow feces, and a loss of the sucking reflex. CHV also causes a necrotizing vasculitis that results in hemorrhage around the blood vessels. [6] Bruising of the belly may occur. Eye lesions include keratitis, uveitis, optic neuritis, retinitis, and retinal dysplasia. [7]
It is also possible for dogs to become infected through a blood transfusion from an infected dog. [3] There are three stages of ehrlichiosis, each varying in severity. [5] The acute stage, occurring several weeks after infection and lasting for up to a month, can lead to fever and lowered peripheral blood cell counts due to bone marrow ...
Canine distemper virus (CDV) (sometimes termed "footpad disease") is a viral disease that affects a wide variety of mammal families, [2] including domestic and wild species of dogs, coyotes, foxes, pandas, wolves, ferrets, skunks, raccoons, and felines, as well as pinnipeds, some primates, and a variety of other species. CDV does not affect humans.
