Well while breeding season is over at Wolf Park (see links). Breeding season here at home just started, my castrated male Jack Russel (JR) Cody of 1 year old was tied to my 8 year old JR female Tippy for the second time this week. They were tied for about 20 minutes this morning and Tippy howled afterwards. Or at least she tried to howl.
It is really stange to see a castrated young male so interested in an older female. There has been a lot of sexual play, but I didn't expect them to tie.
Hopefully it will end soon,
