My german shepard/rott .7yrs.. hasn't ate in about 7 days now,lifeless,was drinking and urinating,now at vet,his blood work was good
X-ray was good,now says there is a spot on his spleen,doing more testing


.but says he woulldn't make it through surgery,too weak.. does anyone know anything this could be... earlier he said it was not cancer

The reason they can't do surgery is because your dog hasn't eaten in 7 days, and is in fact way too weak.

Did the vet recommend any other treatment, any other options?

I find it a bit strange that the vet mentioned that the dog has issues with his spleen, knows that the dog needs surgery, but sent you home with a dog that will likely die if this continues.

I would demand to know what can be done. You paid the vet, the vet is the one that should be telling you what's going on, and if there are any ways to fix it other than surgery. Or at least tell you how to get some nutrition in your dog, strengthen him up so he can have the surgery.

Personally, I'd ask for a second opinion. I'm shocked that this vet gave you no answers, no solutions, and basically sent your dog home to die.

I've posted 2 links for you to refer to so that you can educate yourself about the function and diseases of the spleen before you speak to your vet again. There is nothing like being well informed.
You said that bloodwork was normal, I would presume that a CBC or complete blood count was done?
Because the spleen is a resevior and filter for the blood cells in some circumstances it may rupture. Resulting in a need for transfusions.
A dog can live without his spleen, however cannot continue to not eat and grow weaker.
I'll not go on about the disease, the websites are very informative and straightforward.
I don't know what your vet has done or not done, but second opinion is always a valid option.
I will say that depending on your pets physical condition, which at the moment sounds pretty fragile, if you opt for surgery, you may want to look into finding a nearby specialty hospital that will have the equipment and staff to properly monitor a touchy case such as yours.
Good luck and I wish you and your pet all the best.
