Dogs don't breed when entering love mode.

Affects live 1.14.0 and 1.14.1, not just beta. Also, confirmed does not depend on which food you give them.

I further tested this in creative mode and was able to get dogs to breed by making them move around after feeding them. If I just fed them they would get hearts but not breed. If I fed them and then ran away they would run and/or teleport to follow me and then sometimes seem to find each other while moving and proceed to breed (face each other and produce a baby). However, when I tried this trick in survival mode I could not get it to work. I only tried for 5-10 minutes though, so it might work in survival if you keep trying it. At best it's a workaround. There is clearly something wrong with the dogs' ability to "see" each other in love mode.

Here’s a thought that someone with more knowledge of the code might be able to test. I wonder if the bug is caused by the dog AI prioritizing following the player over other activities? It does seem that the dogs stare at me constantly and when put into love mode by feeding they just continue to stare at me and never look at each other.

Another possibility: perhaps the dogs are constantly looking at the player because they constantly “think” the player is holding meat in his/her hand? It does seem that when I switch from holding meat (for feeding them) to another item or to empty hand—that they do not stop staring at me. Perhaps this is an issue with the hot bar? (I know we’ve had other hotbar/inventory issues recently, e.g. milk buckets and bells, so perhaps one of those fixes did something to hotbar code to cause this?)

Turns out this was reported during the 1.13 beta, MCPE-48269, but no one noticed.

Changelog for 1.14.25.1 says this is fixed, can someone in the beta confirm (@Mann Kristof you first reported this for a beta)?

This bug is fixed in the latest beta version, and the fix will be included in a future update when that is ready for full release (no specific date can be given). We will leave this ticket open as a point of reference until the fix has been fully released.
