@MaryJane While they were standing in front of us. Marlow has to sit for his treats but Leo doesn't know a command yet (but we are working on it!) so he was standing. And yes, Leo was laying down and Marlow came close to the bed. Probably about exactly 3 feet from the bed Leo was on.

@greysmom Thank you so much for all the detailed tips! We've already started implementing these. Leo was neutered pretty recently so hoping with some time plus some more diligence on our part, it will improve. We haven't had any new incidents of aggression. @MaryJane The first time they were each just given a treat. We had just tried to start giving treats since they had be interacting well for a few days and had done this a few times without issue so I am not sure what was different this time. It happened very fast and I figured it was that Leo was still used to guarding food/or feeling like food was scarce and got protective. Since then we decided it was too early to give them treats together. The second time, I was in our master bathroom getting ready with the door open and Leo was laying on a bed in our room (we have several dog beds through out the house and he had followed me in there and laid down). Marlow was in the other room with my partner and then came slowly walking through our master bedroom door. Leo growled and then almost immediately jumped up and lunged at Marlow in the bedroom door way. When Leo growled Marlow froze but did not back away. I heard the growl so moved towards them was able to grab Leo and tell him "NO!". I read online about how important the growl is and that it is better a dog is growling as a warning before snapping because the alternative would be to snap without warning. But I am a bit concerned how quickly he moved from a growl to a lung with a snap. I was right there and able to respond quickly and grab him. Since this incident we've been keeping the muzzle on and staying very close.

Hi - My partner and I have had our current grey Marlow for 8.5 years. We adopted Marlow when he was four and he is now 12.5 years old! He is still healthy and happy but definitely slower these days. We had been debating about whether to get a new greyhound once Marlow passed or have them overlap a bit to help ease the new dog in. We finally decided to go for it and 9 days ago we brought home Leo. Leo is a 3.5 year old male and pretty fresh off the track. The dogs did great together the first few days but since then Leo has growled and quickly lunged and snapped at Marlow. One of the times he caught Marlow's ear. Both times we had taken the muzzle off under our supervision because the dogs were doing so very well together. We've now gone back to muzzle on except during meal times and if we are hanging out with the dogs separately. We really want it to work out but know that if they Leo doesn't start getting along better with our senior Marlow, that it won't be fair to Marlow. Does anyone have any advice on introducing to greys to each other? How long did you have to rely on muzzles when introducing new greys? Is there anything we can do to help Leo not feel threatened or aggressive towards Marlow? Leo is doing so great otherwise and is so sweet so would love for them to get along but also feel guilty for putting Marlow on edge. Marlow is a very passive greyhound so both times this happened he did not growl back and has just been avoiding Leo since these incidents. Thanks for any advice, tips, anecdotes!
