Evening all. We have just rescued a 3 month old longdog. Saluki x greyhound. Today is day two and trying to catch up on training. House training is going OK, a few accidents but getting better. He was also introduced to a collar and lead today too which is going alright. He seems a bit underweight, only about 7kgs with quite a few ribs showing along with hips and spine. He isn't eating particularly well. Had all his breakfast eventually but has only had half his dinner. He is currently on beta puppy which was recommended, the people we got him off had him on pedigree adult kibble and some tinned stuff. I am a new dog owner so please be gentle, but any advice is always welcome. Cheers!
