His gums are pink and everything else seems fine.
Are these signs
(shaking, undereating, shallow breathing, change in
typical behavior) of
a jealous dog?
If they are, how can we stop this?
I don't want him to be this upset, but the other dog isn't going anywhere either.
Duke can be very agressive around other males and is pretty territorial.
If he's still acting like this, he's going to the vet on Monday (none are open right now and none are open on Sunday's either :/).
