Hello, I have an 18 month old female blk/rust dobe (Raven), a 4 yr old female jack russell and three kids (11, 8, & 14 mos). I had a 13 yr old female dobe prior to getting Raven, who got along with our jack pretty well. Only a few scraps, but easily broken up. Raven on the other hand is a totally different story - the two will be playing and suddenly start fighting, with Raven grabbing the jack by the throat and not letting up. Any suggestions as to how I can break this up or is there any hope of her growing out of this???? She also tends to nip at my older children when they run past her. I'm conviced she is playing, but my kids don't enjoy that game. One other thing, I had her to the vet last week and she just went crazy when we came out of the room into the reception area where another dog was waiting. She gets along well with my sister's dogs, but is very aggressive towards others. I plan on taking her to an obiedeince class, which I should have done last summer, but had the baby, so I couldn't. She gets along well with the baby, lets him crawl all over him, take bones from her, etc. Any suggestions would be greatly appreciatedd. Thanks.
