According to http://www.greyhound-data.com/breed.htm the siblings are Kay Kay Anchor, Kay Kay Flag, Kay Kay Paging, Kay Kay Rock and Kay Kay System with two half siblings Betamerica Elite and Betamerica Perks.

I agree about withdrawing the water. You can use a solution of biological wash powder to clean the area if you haven't got anything else. And yes he could be cold or is something disturbing him? Is your heating coming on and the sound of the boiler (furnace) starting up wakes him?

It can take a few weeks for their poop to firm up as they get used to their new lives and become less stressed. I feed Grace Pet Greyhound Food from the Greyhound Trust https://greyhoundtruststore.com/collections/pet-greyhound-feed/products/pet-greyhound-food or Gain Maintenance from Millbryhill https://www.millbryhill.co.uk/pets-c6/gain-greyhound-maintenance-food-p5304/s18328 It also helps with coat condition If you change their diet do so gradually as a sudden change can cause runny poos. Don't let them do anything you don't want them to even if it seems cute at first. For example if you don't want them begging every time you eat or have a snack don't ever give them a titbit or leftovers.

And it's not even half time....

Yes I wondered if it was stud tail but there isn't any waxy/oily secretions or any other symptoms apart from the bald patch and the hairs are broken off not dropped out. I wonder if it's caused by her sitting as the area affected is where her tail bends sharply as it makes contact with the floor so it is the hairs are hitting the floor end on and breaking. If that is the case I think I'll try applying aloe vera to soften the hairs so they bend instead of breaking.

Grace has a bald patch on her tail about 3 inches long but only on the side away from her body. The vet, who is experienced with greyhounds as she used to work as a vet at the greyhound tracks, said it is probably where she has been rubbing against something as the hairs are broken and have not dropped out, but she is not crated and sleeps either on her bed or the sofa. (I'll let you guess where she spends most of her time) My question is, although it's purely a cosmetic condition like her bald butt, and it doesn't bother her or me, can anything be rubbed in to her tail to stop the hairs being broken?

I found this interesting article that explains how old your dog is: https://www.sciencemag.org/news/2019/11/here-s-better-way-convert-dog-years-human-years-scientists-say The dog age calculator is about half way down. My Grace is 58 years old which probably explains a lot

He might think that, in his eyes, the spoodle is behaving incorrectly and gives the puppy warning which escalates the more he's ignored. Could your sister when she's playing noisily with the puppy go into another room?

Another vote for checking her sight. Perhaps the lighting needs to come from a different source to increase the contrast. Have you tried getting down to her level and looking down the stairs to see if the edges stand out?

Others who are more experienced will probably have other suggestions, but have you tried a quick tug on the lead, not a constant pull, and a very firm NO as soon as he notices the other dog and keep on walking? Grace used to have a keen interest in cats but using this method she only now looks but doesn't try and chase them.

She ain't nothin' but a hound dog

No problem here. Using Windows 10 laptop and tried with both Firefox and Google Chrome browsers.

That's why greyhounds need large beds.

Are you sure she is underweight? Greyhounds do seem to be very thin especially compared to other dogs. Greyhound Friends For Life say "The rule of thumb is that you should be able to see the outline of the last 3 ribs, the tips of the hip bones, and a bit of the spine. Usually the ideal pet weight is about 3‑5 pounds heavier than the racing weight. When the greyhound is viewed sideways, there should be a nice curve (“tuck up”) between the end of the ribs and the thighs. Allowing your greyhound to become heavier puts undue strain on the heart and on tendons, ligaments, and joints, which can lead to more problems with arthritis." If you do need to increase her weight I suggest increasing the food at meal times. If you give her bits and pieces at other times she will expect it and it then becomes difficult if you need to reduce her weight in the future. Also check the protein level of her food, it should be around 20% now she's retired.

Do you take her bed, toys etc with you? I think you need to go back to basics and introduce her into this new house the same way as you did when you first got her and got her used to your first house.
