Growling and Biting Agression! Help please!

[pitc9]

Sudden behavior change is sadly often a sign of an animal in pain, so let us get that ruled out first, poor puggie!

That was my first thought also! I hope your vet is able to help you figure out what is going on with her.

If it's not a sensitivity to touch, does she growl at you when you pet her while she's eating her dinner? If so, it sounds like she has some resource and space issues. They're both pretty simple to nip in the bud, so don't worry. If it's resource guarding, teach her "Give" and control her access to resources with NILIF (Nothing in Life is Free - just Google it). If it's a space issue, then it's up to you to manage how you approach her. You can desensitize her space issues to a certain level, but you have to give the dogs some leeway. For example, to get her out of bed, clip a leash onto her to coax her out.

Also, the more anxious you are, the more reactive your dog will act. I have a reactive dog, and it is hard not to feel anxious in certain situations. However, you must exude a sense of firm, loving confidence with your dog. If you're ever in a situation where you cannot feel that way, remove yourself, your dog, and/or both of you from that situation and find a way to re-approach the situation.
