Unknown item on dogs leg

Our dog has recently been brought over from Spain and noticed this on his leg. Possibly getting bigger and smaller one (beige) seemed like a cut but is now forming into a lump  unknown if tick / concerning skin growth / other. It's soft to the touch. Any initial advice or guidance appreciated. Thanks!!!

Hello!  The big one looks as if it's going to be hollow and floppy, perhaps with some fluid inside, and continuous with the dogs' skin.  Perhaps some kind of cyst, but malignancy may also be a possibility.  The smaller one looks nodular with some pigmented dots; again, a benign or malignant lump seems possible.   These are definitly worth showing to your vet, who can see them in context of the patient and is therefore in a position to judge whether removal / testing is a) a useful and b) a viable option.  If you search for 'lump' in the blog, you will find a lot of useful articles.

Thanks Liz!!!...very useful information. I will read the blog and take him to the vet :)
