Senior dog food diets are pet foods that are catered toward the senior or mature pet population. The senior dog population consists of dogs that are over the age of seven for most dog breeds, [ 1 ] though in general large and giant breed dogs tend to reach this life stage earlier when compared to smaller breed dogs.
Pyometra is a result of hormonal and structural changes in the uterus lining. This can happen at any age, whether she has bred or not, and whether it is her 1st or 10th heat, although it becomes more common as the dog gets older. The main risk period for a female is for eight weeks after her peak standing heat has ended. [2]
Ovarian cysts may be classified according to whether they are a variant of the normal menstrual cycle, referred to as a functional or follicular cyst. [6] Ovarian cysts are considered large when they are over 5 cm and giant when they are over 15 cm. In children, ovarian cysts reaching above the level of the umbilicus are considered giant.
A female dog is usually diestrous (goes into heat typically twice per year), although some breeds typically have one or three cycles per year. The proestrus is relatively long at 5 to 9 days, while the estrus may last 4 to 13 days, with a diestrus of 60 days followed by about 90 to 150 days of anestrus.
There are four types of ovarian cysts — functional cysts, PCOS cysts, benign ovarian tumor and malignant ovarian tumor — that range from harmless to fatal.
It is common for many women to develop a cyst in their lifetime. [4] At times, these can go unnoticed without pain or visible symptoms. A cyst may develop in either of the ovaries that are responsible for producing hormones and carrying eggs. Ovarian cysts can be of various types, such as dermoid cysts, endometrioma cysts, and the functional cyst.
