Hi! My dog is a rescue and we were told she is a boxer mix. Angel is really tall so she could be anything! Most people say she is a bullmastiff cane corso mix. She is a very large dog. We go for many walks around a pond (we live in Ontario Canada) so when I noticed this red pea-sized lump I guessed it was a splinter? It has not gone away and its been over a week. I am planning on taking her to the vet this weekend but I have been on google reading about possibilities and im super scared and worried now!!! It is not bothering her at all but then again she never yelps or makes sounds she is a very laid back dog. I have never heard her yelp and ive had her over a year.. What could it be? Please help me so I can stay calm until the weekend im really really worried.
