How Long Can A Dog Last Without Eating Food?

A dog can survive for quite a while without food but it depends on their health and physical condition before the period of starvation. It is said that they can go without food for about three or four weeks without access to food. Thus they can survive for a longer period than human. But food is a source of water too apart from the daily amount of drinking water.

But it is harder for a dog without water. Water deprivation would cause dehydration and in extreme hot weathers it can even lead to short in as short as a day. But otherwise the longest period a dog can survive without water is as long as a week. Dogs ideally need fresh water daily just like humans. Salt water can create problems in dogs and many also believe that it can cause diarrhoea.

My golden retriever has a elevated b.u.n of 37 and is on a prescription diet by my vet - how long can she go without food?

My dog has not eaten in 4 days....she still goes outside for walks and uses the bathroom...what could be wrong??? Why won't she eat???

The first question that people ask is why would you want to know that?? Well I want to know because my dog ran away! Why would you think negative like someone is starving their dog?? What about emergencies you dumb idiots!?!?!

Dont be so mean and feed your dog are u really tht sick in the head to do something like this

Makes me wonder why anyone would want to know that.

Our 13 yr. Old dog is on medication because they found fluid on the heart and a heart problem, She's showing some improvement now but she's stopped eating but drinks plenty of water. I'm concerned because it's been 7days and now she has diarrhea.What to do? I hate to take her back to vet because they may want to put her down :(

I wanted to know because my aunt was found dead in her house, last seen two weeks ago, but her dog is still alive. We are trying to figure out her estimated time of death before hearing from coroner's.
