I have a German shepherd mix that I just rescued less than 2 weeks ago, and she a lot throughout the day. We will walk

Customer: Hello! I have a German shepherd mix that I just rescued less than 2 weeks ago, and she poops a lot throughout the day. We will walk and she will poop on the walk, and then come inside and poop again 15 minutes later. Shes been having frequent accidents.
JA: Hi there. I'll do all I can to help. Has the Shepherd been eating or drinking more than usual?
Customer: When she drinks she chugs it down as if she hasnt drank in years, but otherwise no
JA: Does she also seem more tired than usual?
Customer: No she still has a lot of energy. Shes 5 months and has that puppy energy
JA: What's the Shepherd's name?
Customer: Gwen
JA: Is there anything else the Vet should know before I connect you? Rest assured that they'll be able to help you.
Customer: Not that I can think of. We are back outside again after walking less than 15 min ago, and she is pooping and it almost seems like she’s having difficulty with getting it out Customer: Chat is completed
