Why is my dog acting really weird?

Well, I will say one thing that's a relief. It has nothing to do with his health. Many times, I do not encourage owners to go on vacations without their pets, but sometimes, things have to be done. But anyways, he is suffering from something called separation anxiety. I'm sure you've already heard of this term, and are well aware of its meaning, but let me break it down for you in your specific situation. You're dog is confused, and is alert because he is still wondering what happened to you all that time you were gone. Spinning in circles is a sign of excitement for a dog as well, and I'm being very clingy is normal. Just stay with him for a couple days, and see if things clear up. I can assure you that everything that's happening is emotional, not physical. I hope I helped sweet heart, you're dog really loves you, be proud.

Well, a lot of things could be wrong. If this is the first vacation you've taken, or the longest one, the clinging could just be because you've been gone for so long, or he's just not used to it. He could be hanging around your brother because he thinks you're just rejecting him instead of trying to make him stop acting that way. It's very unlikely, but it could also be a very late reaction from the tapeworms, or another type of worm. Pills are extremely helpful, and they usually work, but sometimes they don't, or have side affects, and those could just now be setting in. The water deal is probably just because he's missed you for so long, and is still trying to get over it. If you had someone look after him, they may have accidentally altered his diet, causing his OCD issues to kick in. I would advise you to take him to the vet if this behavior continues for 3-5 more days. If you don't think any of my suggestions are the problem, you could call his vet if you have the number, or find another local vet in the phone book. I really hope this helps, as I know what it's like to have a possibly sick dog and not know what to do. I really hope your little guy gets better by tomorrow, as he should! Good luck with him! :)

I hope you had a good time on vacation. I love Shih Tzus! They are such sweet little dogs. You shouldn't allow him to beg for attention like that. That is bad behavior. It sounds like your dog wants more attention than usual. I'm sure he missed you guys! Again, don't allow your dog to beg for attention. This leads to very poor behavior. Never allow a dog to climb on you. It sounds like he might have be anxious because of the storm. I would not use the poison that vets give for worms, as it can have very bad side effects on dogs. The same goes for those flea/tick pills! Those pills are nothing but poison and chemicals. Your dog could be having a reaction to one of the pesticide pills you gave him. That is why I will not use these things on my dog, EVER! A friend of mine has a Golden Retriever that suffered a serious of multiple seizures after taking Heartguard Plus. I used Revolution on my cat a few years ago, and he lost huge patches of hair where the medication was put on. Dogs don't get OCD. The cause for his excessive thirst could be diabetes insipidus. Get your dog to the vet and have his blood sugar tested. Symptoms of diabetes insipidus are excessive thirst and excessive urine volume. It can be caused by a head injury, infection, loss of blood supply to the gland, sugery, or a tumor. Certain drugs, high levels of calcium in the body, and kidney disease can also cause diabetes insipidus. I recommend you get your dog to the vet and have an MRI of his head, Urinalysis, and Urine Output test done. My last dog suffered from diabetes insipidus and I managed that without medication and a diet consisting of oily fish, cooked beans, sweet potatoes, jerusalem artichoke hearts, garbanzo beans, a variety of nuts, plums, peas, rye, yams, wheat bran, mung beans, brewer's yeast, figs, millet, sweet rice, radishes, plums, water chestnuts, tangerines, string beans, coconut, asparagus, flaxseeds, mulberries, lemon juice, green beans, lentils, oats, pumpkin, chives, rice, soybeans, winter squash, buckwheat, olives, mandarin oranges, kohlrabi, soy milk, and pears.
