Just got myself a Patterdale terrier and toy poodle cross. I am normally a cat person but fell for her. Any thoughts on what type of size she'll get to??? She is crazy with the cats , she just wants to play but I feel I need to nip it in the bud. I need her to stop waking in her crate when the heating comes on at 5 and whining for an hour, she's lovely I just need advice ... Lack of experience n all. Xx
