I won't put the picture up because you don't want your images edited but I put it through Lightroom and tried auto white balance and it looks like a different picture.
There are techniques to get white balance properly setup, have a search on here - I think there are some tutorials - or have a look on YouTube. Basically you use a piece of grey card. You take a picture with the grey card held next to where you are focussing, you then take your pictures as normal. Once you put them all through Lightroom you find the grey card pic and in the white balance settings you use the colour picker and click it on the grey card. It sounds strange when you first try it, but it works.
You can just move the white balance settings until you are happy. I'm guessing the dog is white, so that should be your target, just move the white balance until it's white and see what you think. It's usually a bit strange as it's such a big deviation from what the camera produced, so it feels wrong. The other thing is we are used to this. For so long we have seen average family snaps and more recently phone pics, we don't look at them and think 'oooh the white balance is way off there', you only think like that when you start to take photography seriously.
Or when you notice your white dog is orange I guess!
I've spent a serious amount of time learning, but it's worth doing. There are some really good YouTube videos that can help with so much of this stuff, and they make it sound simple too, and show you how to do it. So much better than just reading a book, though books are great too. Pic your subject, and watch a few YouTube videos on it. Then put it into practice, when you are happy pic your next subject. I don't know where you are starting from but this is my first DSLR so I needed to learn everything really. From all the camera settings, not just what they are and how they work, but really how they work, and how they are used in photography. I needed to learn all about exposure, aperture, ISO, light, flash and loads more. I still feel like I know nothing, which is why I enjoy tryinto answer questions and offer tips - if I can help a little I guess I'm learning something! Flash is my current topic. I've learnt a fair amount but I'm putting it into practice, I've got the equipment but I need to make sure I know how to use it.
It's good that you are making different pictures every day. They say you first 10,000 pictures are your worst, mine are all rubbish, I'm looking forward to seeing what I can produce for number 10,001!
Keep at it, and tweak that white balance until the dog looks like the colour it should.
