I have a 5 month old PBGV and we currently live in Germany. Its starting to get colder in the mornings and it stays dark till nearly 9am. My pup Tara, is sleeping later and later each morning. She used to be rushing out of the crate to go to the bathroom but now is totally lazy and sleeps till 9am or later. She's not interested in her food right away either. She opts for waiting till she's done napping to investigate her bowl. She is on antibiotics for a UTI so I am wondering if its the recovery period or is it the seasons?
