Respected user, hi I evaluated your query thoroughly.
* 
Frequent urination has to be correlated with all other symptoms  as
   burning / pain , weight alterations , appetite , other systemic issue 
   forcing kidneys to expel more urine ; 
Diabetes work up , 
Ultrasound etc.
* So unless we come to final conclusion of diagnosis , treatment is not 
   proper .
* Till then I suggest
- check for fever
- keep genitals clean , dry
- maintain hydration , proper diet intake .
- watch for lethary / other systemic derangement 
Hope this helps you.
Welcome for any further queries.
Thanks for using Health care magics & reviewing my answer thoroughly. 
Wishing your Angel fine recovery from the same.
Regards dear take care.
