A dog with degenerative myelopathy often stands with its legs close together and may not correct an unusual foot position due to a lack of conscious proprioception. Canine degenerative myelopathy, also known as chronic degenerative radiculomyelopathy, is an incurable, progressive disease of the canine spinal cord that is similar in many ways to amyotrophic lateral sclerosis (ALS).
The vitamin D receptor (VDR also known as the calcitriol receptor) is a member of the nuclear receptor family of transcription factors. [5] Calcitriol (the active form of vitamin D , 1,25-(OH) 2 vitamin D 3 ) binds to VDR, which then forms a heterodimer with the retinoid-X receptor .
In some dog breeds, symptoms appear to progressively worsen, but research is not consistent on this point. There also is some evidence that affected animals partially compensate for the condition by cognitively learning alternative methods for moving or to determine distance, and thus appear to improve because they become less accident-prone.
The VDR is widely distributed in tissues, and is not restricted to those tissues considered the classic targets of vitamin D. The VDR upon binding to 1,25(OH) 2 D heterodimerizes with other nuclear hormone receptors, in particular the family of retinoid X receptors. This VDR/RXR heterodimer complex binds to the specific VDRE in the promoters of ...
Hypertrophic Osteodystrophy (HOD) is a bone disease that occurs most often in fast-growing large and giant breed dogs; however, it also affects medium breed animals like the Australian Shepherd. The disorder is sometimes referred to as metaphyseal osteopathy , and typically first presents between the ages of 2 and 7 months. [ 1 ]
Necrotizing meningoencephalitis (NME) is a fatal inflammatory central nervous system (CNS) disorder in dogs, where an extensive cerebral necrosis is associated with a multifocal, non-suppurative meningoencephalitis of the neuro cortex.
Thyrotoxicosis is a rare side effect in dogs receiving levothyroxine treatment due to the half-life and poor absorption. Thyrotoxicosis occurs when a dog is either given too much levothyroxine or has issues with metabolising it. Symptoms include: polypynoea, anxiety, tachycardia, aggression, polyuria, polydipsia, polyphagia, and cachexia. [2]
Pituitary gland tumors are very common in the canine. A productive form arising from the anterior pituitary is the primary cause of Cushing's disease of dogs. This tumor causes excessive production of cortisol from the adrenal cortex which leads to the classic signs of alopecia (hair loss), polyuria (excessive urination), polydipsia (excessive water drinking), and a pot-bellied appearance of ...
