Neutering of German Shepherd Dogs: associated joint disorders, cancers and urinary incontinence

​

You may think why add a link to neutering of German Shepherd dogs.  But this affects all breeds of dogs and the links of early neutering or neutering at all.  

It was a study done on Hungarian Vizsla many years ago which gave us our first insight that spaying or neutering was the link to cancers. Since then other dog breeds have been assessed.  One of the most common things the Vizsla will die of is Spleen Hemanigosarcoma. 

We have to remember all of us die be it human or dog.  Humans die from heart disease or cancers it would seem. Dogs are the same. This does not make it any more less important but it helps us understand more that unfortunately all dogs will die.  I wish they could live for ever. 

Weimaraners for years had MCT of the skin and they are a breed which you can not escape them.  
But now proven it's the spaying or neutering.  
German shepherds often die from a brain tumour. 
Vizsla hemanigiosarcoma. 
 If you want your dog to live a long life then spaying or neutering much later is more advisable. If at all. But it is down to the owner to be responsible and not let them have unwanted puppies. 
​It is worth reading the report ive linked above on German shepherds.

An increase in some cancers sometimes is also of concern with neutering, particularly with osteosarcoma (OSA), hemangiosarcoma (HSA), lymphoma (LSA) and mast cell tumours (MCT). A study on OSA in several breeds found a twofold increase in neutered dogs relative to intact dogs (Ru et al. 1998). In spayed females, cardiac HSA was reported to be four times greater than that in intact females (Ware & Hopper 1999), and in spayed females splenic HSA was reported at two times greater than in intact females (Prymak et al. 1988). The occurrence of LSA was found to be higher in spayed than in intact females (Villamil et al. 2009). Cutaneous MCT, as studied in several dog breeds, was four times greater than that of intact females in neutered females (White et al. 2011).
