Hi Pug Mama! Congratulations on the new addition to the family. Love the above photo. Medical of course is the first thing-scary and not so scary things-to rule out. If you have not already done this, and if it is possible at this time, bringing a simple urine sample in may be helpful-they can give you the details on how to do this (whether to wipe her first before she goes, what time of day, etc.) If this is not possible I would still try to catch a sample to see if there is anything very obvious such as blood or cloudiness-anything that is not "perfect").
Have you ever seen her empty more completely away from the foster home or yours? Meaning somewhere where dogs are not already frequent visitors etc.-like a supermarket's grassy area or sidewalk or somewhere more private/hidden? Two of our dogs (Jada and Fiona) were found together, different ages and apparently different breed mixes and both female, one spayed and one unspayed (at that time). But both HAD to be walked away from their little sub yard and cabin before they would go potty. We walked them closer to the wooded section where we have a large tree trunk pile and a little embankment where they would go immediately. We have other dogs but they were not even sharing the same spaces (yet). And still it seemed to be the issue. This became unnecessary in time once they were more settled in. Maybe try a more private yard or section of the yard that pup #1 does not frequent or creating a space just for this pup for a while by de-scenting, bleaching an area (that may harm your grass, etc. thou) and hanging up a curtain on a laundry line for her privacy.
Starting at the beginning as if she were a puppy ...we have let puppies out every 2 hours with success (overnight maybe just once). While we really like our crates as do our dogs, people and dogs got along without them before they were commonly available. Small sectioned off areas in a house or room can work wonders if potty issues are the only concern. Adding outlet covers and safely removing or blocking off any possible concerns would raise safety levels giving you more peace of mind as well.
Praising...as soon as she has completed this task and not during.
Time and space...she may need extra time. Possibly try walking her for potty in the same spot/spots like the perimeter of the yard/separate yard/or that special section that belongs to just her. And just wait longer till you absolutely think she is done and add a minute or two just in case. This potty time is only for potty so try not to say or do anything to distract her other than the praise afterward and maybe the initial go potty phrase that you use.
Submission...sometimes puppies and adult dogs will urinate right in front of you or another dog. This can stop over time. Our adult dog Danny did this when we would come near him, for a while after he came to live with us. But that is a very distant memory (approx. 14 years ago).
Danny, Jada, and Fiona none of these dogs would be called nervous or overly submissive (certainly not to other dogs!). And other pups of ours have had medical issues causing less urine output that required the veterinarian's assistance/surgery or meds.
Congratulations again and thanks for searching for answers...Sarah
