Hello from a fellow SoCal resident! My buddy Aston (featured in my avatar) passed away in 2014, but I still lurk and occasionally contribute because GT is great Aston's weight held steady at about 72lbs, and he was a tallish guy. He had a high prey drive, resulting in the occasional false-start lunge after a squirrel or darting feral cat, but he never pulled hard enough to hurt my shoulder or pull me over. I did slipknot the leash around my wrist to avoid dropping it, so the risk of dislocation was there, but I favored that risk over the risk of Aston taking off. Aside from the mini-lunges, back when I first brought him home and he was still getting used to the new sights, sounds, and smells in my neighborhood, he would "statue" during walks. There are lots of GT threads about this, mostly from new adopters This was problematic because I couldn't very well just sling Aston over my shoulder and carry him home if he didn't want to walk anymore This behavior diminished somewhat with time as he got used to the new sensory input, but in the meantime, I did find myself in jams, especially if we were far from home and/or I couldn't afford to sit and stare at a squirrel with Aston all day. My solution in the beginning was to shorten the leash, pin his shoulder to my hip, and get him moving in a few tight circles with a high-pitched, happy "Let's go!" -- that would often shake him free of whatever was causing him to mentally freeze, though I would often have to repeat the maneuver on the same walk. He was also very reactive to seeing and hearing smaller dogs, so I ended up clicker-training him to look to me when triggered instead of fixating on other things, which had the indirect benefit of giving me a way to get him out of the statue mindset, but that took lots of practice. In the meantime, small circles I could never lift Aston outright, though I had always wanted to train up with a duffel bag full of sand, just in case; I never got around to it. He ended up with progressive lumbosacral stenosis that depleted his hind-end strength to the point that he was sometimes unable to hop into the back of my car on his own. I couldn't lift his whole body, so I would instead bring him perpendicular to the edge of the car, manually lift each foot and place it inside the back of the car, then get behind him and happily yell UP UP! with an upward boost to his hind end as ergonomically as I could manage. The maneuver was surely awkward-looking, but Aston kindly obliged with the help of lots of associated treats. My big fear was that Aston would suffer a major illness or injury one day and would need to be carried to a car, and I wouldn't be able to do it alone. I was married at the time, so often had a partner at home; but otherwise, I got to know my neighbors and identified who the 'dog people' were who I could call on if I needed help lifting my buddy. Aston was a veteran home-hound when I got him at age six. Upon adopting him, I proceeded immediately with alone-training per my adoption group's instructions, but found that he already had that framed certificate. When I first got him, I arranged to take long lunches to drive 25min to/from work and home to walk him at lunch, but found more often than not that Aston couldn't be bothered to interrupt his couch time to go outside during my stop-in (?!). I then learned after a while that he had his own way of doing things -- he would time his major drinking to when he knew he wouldn't be alone for long stretches, still consuming lots of water overall, but only sipping during the day if we were away -- and the routine for him was the same if we were home all day on weekends. He was used to going out for walks pre-work and post-work, but would only stand outside in the backyard and stare if I let him into the backyard during a lunch break from work. So, eventually, I gave up regular daily checks, and he would often go 9-10 hours between potty breaks. I know that this is not a safe assumption for any dog, but it worked in Aston's case. In your case, being able to go home during the workday is great you would get to know your dog, and go from there. As for the tiny apartment, I had a two-story condo at the time, but each floor was tiny and crowded with furniture. Aston was allowed on our one sofa, so he parked himself there most of the time, and then joined us in the bedroom at night on his own bed. He would do 30-second indoor zoomies at night, but always managed to avoid smacking into furniture, which was amazing given that he was a 72-lb bouquet of elbows As for the weather in SoCal, I did have to exercise care with Aston despite the mild-ish weather compared to other parts of the U.S. He actually got chilly enough indoors in the winter that I found him pacing around at night; I bought him some lightweight jersey-knit four-legged jammies (with a Camaro print!), and he stopped pacing and was able to sleep through the chilly nights thereafter. Because he was so thin-coated (and dark-furred) and had no insulation via fatty tissue, he would also FRY in the sun during warm stretches. I was careful to avoid walking him in the middle of hot days, and would seek shady routes. His back would heat up to the touch so quickly!! I wanted to get/make him a light-colored sun shirt to reflect some of the direct sun; I probably could have just put his head and front legs through a cheap white undershirt, in retrospect. After walks in warm weather, I was always careful to wipe his chest, armpits and paw pads down with a cool rag to help him normalize. I can't comment on the whippet things, since I don't have any experience. Fostering the whippet for a bit sounds like a good idea, though? The only downside I can think of in looking for a petite, low-prey greyhound is that you might end up waiting a bit, as petite (especially female) greys and low-prey greys seem to be in highest demand. However, dark-colored, giant, bouquet-of-elbows goofy dudes are generally bouncing around in abundance <3 Best of luck with your search!! It has been a while since I posted here about Aston. I sure miss that guy. Greyhounds are the best.
