Get Daisy to the vet if she’s eating non-stop. Reestablish a routine for EVERYONE in the house. This may include feeding all the dogs in their crates for now.
I would also encourage getting a behaviorist in the home, to see exactly what’s going on. There may be an underlying behavioral issue that you aren’t seeing.
Is Jessy a herding breed? How long have you had her in the home? What sort of training have you done with her thus far?
I agree- the sooner you get to the vet, the better. If you let it wait, it may become costly if it is in fact infected. Good luck!
Please take your dog to.a Vet as soon as you can. Something is obviously wrong. He could have an infection needing treatment or something else. All lumps need checking too. This is bothering him a great deal if he’s constantly licking the area and whatever it is needs to be diagnosed and treated. Hope he’s better soon.
