Hi....so, I am no vet, but a friend had some similar issues with her dog, and the dog had portosystemic shunt. This is a lucky guess, you need to listen to your vet or get a second vetenerian opinion.
But I agree with you, you have to be careful not to put her under some treatment that is uncomfortable to her, or more aggresive than the disease.
I hope you will come to the bottom of this, and If She is ok and functional, try some natural remedies too (it can’t hurt).
Sending you get well wishes
Sorry to hear that, but She needs time to adjust and crating is not helping.
I never crated my dogs and they never distroyed anything.
My advise is to work with her more, obedience, longer walks...so She doesn’t feel neglected and let her find her own safe place.
I wouldn’t give her medications, just time.
Close those rooms with fancy furniture and leave her somewhere your smell is, bedroom maybe?
Panting and saliva pools means a lot of stress, so get her out of the crate If she is not used to it, dont give her prozac.
You need time, mental and phisical stimulations and lots of love
If it happened only twice and never again, don’t be alarmed. Maybe he ate something that upset his tummy (beside his meals).
Does he has a reflux and swallows his saliva often?
If not, monitor his behaviour, divide his meals in small portions and give them more often...
Oh, and add water to his meals, specially If he eats dry food because they are known as poor drinkers.
My basenji had similar periods, when in puberty... I learned he was eating too much protein. We switched to raw, I have cut his portions and he is eating regulary.
He will eat anything when with other dogs, that doesn’t mean he likes it, he just doesn’t want other dogs to eat it.
Relax, offer him food after walking. Get him tired, come home and give him food. If he doesn’t want it, pick it up.
I prefer raw food, but that doesn’t mean That’s your only option. My problems are gone since on raw. Do your research and find food he likes. Wach for proteins, If you feed kibble, up to 24% of protein is enough.
