It does seem to me like a symptom of anxiety. Dogs don't understand spite at all. We misunderstand a lot of things dogs do as spite when generally it is stress , anxiety, fear, and confusion. Dogs are creatures of habit. Until a strict routine the dog can count on is established things can be very confusing and stressful . Some dogs adjust faster and easier others have a hard time. The best thing to do is establish a routine to always go outside before you leave the house..even if it is to run to the store for 10 minutes. Then leave her a toy she ONLY gets when you are not home..make it a very high value treat toy. Something she has to work on. Then leave casually, try not to make to big a deal out of it . Make sure she sits or lays down before you leave..this will take some teach her.
Invest in something like this and only leave it down when you leave. It will save you at least from the mess. It is possible that this is something you have to deal with , but more often then not with enough consistany and making sure you give her every oppurtinity to go outside before leaving and after comming back. And giving the dog a distraction while you are gone will help some. Also.
Get a cd like this. It may seem really weird..but I got a sample song and played this for lela when she is having some issues being a little ....frisky lol..she seemed to really respond and calmed down. The music is set for certain beats and rhythms to slow your dog's heart rate and basically soothe them..it does the same for them as it would for us basically and it really is a calming music I personally love these cds.
Also leaving something of your smell can help but some dogs that isn't going to be easy..Lela would just chew a shirt if I gave it to her lol. Generally if you are playing with her with her toys..her toys should smell like you IMO.
For natural remedies , now I love them..for me.. i don't mind taking some risks with herbs on myself without the consent of a doctor but with my dog I just wouldn't recommend it. before trying anything..even natural consult your vet first. The only thing I would recommend with a pretty clear conscious is
This herb reduces anxiety in dogs that are stressed out. It calms the nerve as well as induces sleep. You can give chamomile tea to your dog before a long drive or soak a treat in the tea.
Although this is one of the safest herbs, some dogs are allergic to the plant, so please check for sensitivity first before applying it to your dog. Also limit the use of this herb on pregnant dogs.
( hence why I say ALWAYS check with your vet..all dogs are different)
Oat is an excellent nerve-calming herb and is nutritious as well. Cooked oatmeal can be added to your dog's food.
So try some of these suggestions and remember no advice is better then your vet ^_^
