Yep, that happened to me--senior or special needs (I had a diabetic cat in the past, so chronic illness is no stranger in this house!), ended up with the Ginormous Galoot, soon to be 2.5.
Good luck, any way it shakes out!
My adoption group does rehome biters--I have one. Bites are an extreme reaction. That and the other behavior shows your grey needs more than you can give her.
Some greys just need a home without children or with only one owner. Call your group NOW.
I've gotten four greyhounds trained to use open-back stairs. Each one took a little time, but I got thru it and they know FOOD is at the top of those stairs!
Fuzzy took the longest, she wants to go up ONE specific side of the stairs and won't budge until she can. Roman was difficult because he's HUGE and I had to push and lift him to get his feet going.
Roman is the whinest dog I've ever had. He is convinced I will forget mealtime, outs, that he even exists...I have gotten him to do it less, but he still does.
Fuzzy MUST LIK-LIK any and all scabs til they are removed, so I think it's itchyness, too. I use a spray for feline hot spots if the pups get too obsessed about licking and make it worse.
Roman came home kinda dirty (he's white with fawn) and sorta smelly, but he's just kinda smelly now. He had spots/ticking, but boy howdy does he have SPOTS now. I'm guessing the Florida kennel was all shaded and now he gets to sunbathe and all.
If you are bringing just one or two hounds, the Doubletree up the hill (and it is UP THE HILL) is recommended. I've got reservations at the Super 8 down the hill from the SJ. I may have to get Roman the Galoot to pull me up the hill by the end of the weekend, LOL.
Her master's voice? Picking up signals from Alpha Centauri?
My Fuzzy is a terrible scab picker, I have no doubt she'd have picked those stitches, too.
And another with the obnoxious boss that can't keep it short and sweet.
I think giving G CBD oil helped his bald thighs fill in, plus he now has bunny-soft furs.
And Sweep, you have our permission to chomp any one who make fun of your bum!
