New skin growth/lump

Hiya, We have just found this on our dog today at the back of his right front leg. He is 8 years old and a Cavalier who has quite a lot of fur so we haven’t noticed it, I only found it as I felt it when stroking his leg. He was only at the groomers in December and is cut quite short so we are certain it wasn’t  there before then and think the groomers would have noticed it if so. I have googled different types of growths/lumps/warts and just cant match it to any set one with how it looks. I will attach a picture and if you could take a look it would be much appreciated. We are planning to take him to the vets for it but just want a first opinion also. Thanks very much.

Hello!  There is something called a 'strawberry lump' or histiocytoma; (say:  hiss-tee-oh-sight-oh-ma).  These tend to appear in quite young dogs, stick around for a while and disappear again.  However there are also warts, polyps and cancers and other possibilities.  If your vet thinks that a histiocytoma is likely, they might ask to leave the lump for a while to see what happens, as they sometimes disappear by themselves.  However histiocytomas are most common between one and three years old.  Furthermore, if they think it may be something more sinister, the vet may want to treat or biopsy right away, so your plan to get it checked is a good one.
