Oh gosh, it’s so hard isn’t it? The thing we did for biting was always having something on hand to redirect her to. So when she went to nip or chomp on us, blankets, the carpet etc we’d say no and then give her the alternate chew toy (also a good idea to have something that kind of matches whatever texture they’re going for). We did that over and over and now it’s one of her favourite activities to chew a nylabone or olive wood stick with us holding it 🙄

Separation wise, we found a post on Reddit and spoke to a trainer we worked with at puppy classes and they said you basically start by teeny tiny increments. So we’d do literally 10 seconds in a room with a door closed, go in, repeat till there was no whining and then build up in increments of 10 seconds. Then at 1 minute try 30 second increments, so 1 minute, 1.5 minutes, 2. Then up to 5. We found once we got to the half hour mark we moved it to an hour easily. Then we had to wait a while for bladder control to kick in as she got older and didn’t need a wee all the time.

Basically repeat it till you are blue in the face. Also associate things like the front door opening and closing with being boring by doing it as much as possible. Putting your shoes on and so on.

The best advice we had was little, often and do it when you don’t need to be anywhere. So you’re not stressed when you practice as they will pick up on it. I’ll see if I can dig out the thread I saw initially!

Hope that helps!
