I've seen a couple of different types of staining on Havanese.
The pinkish-orangish staining is usually caused by saliva, whether it be around the mouth or on feet. Sometimes that pink staining on the feet can be a sign of allergies or just boredom.
There is a grey dingy stain that comes from blacktop (tar/oil residue), which my white girl would often pick up when we went to our training class. I had to wash her feet as soon as we got home each time so it wouldn't permanently stain.
Then there is the yellowish staining on feet or between legs or under the rectum. This is usually caused by urine or fecal matter. This can be removed with an enzymatic shampoo.
However, there are a few dogs, including two top champions in the show ring here, that appear to have a yellowish stain to their feet, but I think it is just their coloring. Both are groomed by people who are very diligent and wouldn't allow urine or fecal staining, so I'm inclined to think it is part of the hair instead.
All in all, I can't see the pup in question to tell what kind of staining you see, but hopefully some of the above information will be helpful for you.
