Firstly do you have a back garden? because it is safe to let your puppy into your own back garden straight away regardless of injections.

If you do have a garden my advice to you would be to ditch the puppy pads immediately and get her going to the toilet outside, using puppy pads is just reinforcing that it is OK to go to the toilet indoors. Take her out as soon as she wakes up, after every meal, every play session and at about 20 - 30 minute intervals throughout the day while she is awake. Use a key word when she goes to the toilet like "be quick" "toilet" "wee wee's" etc. Pick one word or phrase and stick to it and use everytime she performs. When she is weeing or poohing outside as well as using the key word give her praise at the same time so she knows what she is doing is correct.

As for the crate. At this age never just leave her to go to the toilet in her own bed, she is crying to let you know she needs the toilet so she must be let out to go. Dogs are clean creatures and do not like to deficate their own bed so it would just be cruel to leave her, and remember a 7 week old bladder is very tiny so they cannot be expected to hold it all night. Puppies do not have full bladder control until about 6 months old but many do manage it much sooner. If she cries, take her outside to let her go to the toilet, and put her back in her bed with no fuss. She will soon learn that it is only toilet time and not play time.

Puppies are like little sponges and pick things up surprisingly quickly.

Good luck with everything, I'm sure she'll crack it all soon
