So the dogs are obviously overcrowded in the house, are never get let out, stink of urine, have urine soaked feet which obviously leadsmtomother horrible and painful conditions and are being left to breed freely in those circumstances...but you dont know what to do and dont want to get her into trouble?
I will be gentle here....firstly I think this woman needs some help both physically and possibly mentally if she cannot see whats wrong in what shes doing....secondly can you honestly say you dont know what to do or is it that you just cant face it?
Is she a good friend which makes it very difficult but then again if that were so you would have been aware of this situation some time and I hope you werent. You can have a very straight word in her ear about the dogs welfare and offer your help or you need to get help. If you do not feel you can go directly to an animal welfare organisation and she is over 50 and you feel she is neglecting her own welfare as well as her dogs which to be honest she is if they are toiletting in the house, you can go to your local branch of Age Uk and tell them the situation is urgent and you have to leave it in their hands to investigate or support her and dont leave any of your own contact details so that they have to take it up or/ and you can contact social services adult help desk.
Please do something, this is a terribly sad situation for both the woman and the dogs and expected puppies. If this is a litter of 10 puppies you will soon be looking at 25 or more dogs running around in the house.
Having no natural sunlight will affect their skin, no natural light affect their eyes, ...did you notice their nails if they are not going out on walks...their pads...heaven knows what their joints are like...what diet they are on...
Please do something...maybe start today by knocking on her door to offer some help and to see how bad the situation is to help you make the move...
