I have a 11 week old pup. We have an area of gravel in our garden which she likes to dig and eat the gravel, which we don't want her to do.
We started by trying to tempt her away with a treat or toy, but this stopped working as she prefers eating the gravel to treats/toys. We ended up picking her up to move her away, however she got quite aggressive when we did this. She started barking/lunging obviously as a warning, but we needed to move her because she was eating the gravel, so when we tried to pick her up she went to bite us. This has happened twice. We have now fenced of the gravel so it's not a problem anymore, but I'm concerned about the behaviour, could this be resource guarding? Or is it normal puppy behaviour? We have a behaviourist coming next week, but I'm just looking for opinions in the mean time.
