My jack russell puppy (7mos. Old, regular vaccination records) has recently become ill. He threw up twice yesterday morning (ended up the culprit was 1/2 a peach pit... the other 1/2 was found still in the trash). He, however, threw up again twice this morning. It is little throw up that is more muscey... it has no food in it. His eating habits and bathroom habits are otherwise normal, and he is drinking water (I have not fed him yet today).

Is this just a puppy thing related to something he ate? (He does eat plastic sqeakers out of toys... he chews them up, but if I'm not watching him carefully... well, he's a jack russell and will eat anything that doesn't eat him first). I've taken him to the vet for a similar incident, and it ended up being something he ate. Any suggestions?

I have a Jack Russell and a Jack-a-poo and they both trow up often but its because they eat things they shouldn't. It sounds like you just need to keep an eye on what he's been eating lately

Peach pits can be toxic. Do you suspect he may have eaten the almond like inner part? You may want to at least talk to the vet about it.

Rubber squeaky toys can be fatal too, the pieces blocking the air way or digestive tract. The pet stores are full of toys that many dogs will quickly chew up into
Pieces they could choke on or cause intestinal blockages. If you are not
There to watch, stick to sturdy stuff such as Nylabones and Kongs. Keep a
Close eye on chew toys and quickly discard anything that is coming apart in
Pieces. Rawhide is especially bad because it swells after being swallowed.
As you can see, these problems are the worst with, but not limited to, large, aggressive
Chewers such as Labs. No tour of the dog guide school is complete with seeing the display of objects their vet staff has removed from puppies.

You really need to keep an eye on him when you can, otherwise, crate him. Other dogs may not be as bad as the young Labs I am plagued with. Still your house and dog
Will be much safer with the dog in a crate when you are away. The dog may be
Happier in its den than loose in the house. It relaxes, it feels safe in its
Den. It rests, the body slows down reducing the need for water and relieving
Its self. Dogs that have been crated all along do very well. Many of them
Will rest in their crates even when the door is open. I think the plastic
Ones give the dog more of a safe, enclosed den feeling. They are harder for
Dogs to open too. Metal ones can be put in a corner or covered with
Something the dog can't pull in and chew. Select a crate just big enough for the full grown dog to stretch out in.

Leave it some toys. Perhaps a Kong filled with peanut butter. Don't leave
Anything in the crate the dog might chew up. It will do fine without even any
Bedding. You will come home to a safe dog and a house you can enjoy.

A dog that has not been crated since it was little, make take some work.
Start just putting its toys and treats in the crate. Praise it for going
in. If you have been able to trust it with any bedding, put that in the crate.
Feed it in the crate. This is also an easy way to maintain order at feeding
Time for more than one dog.

I would suggest a visit to your vet, for some lab work and possible x-ray. What else could he have gotten into? If he got to the peach pit with out you knowing what else was in there that he may have eaten. Plastics usually don't show up on x-rays but it will show if there is a hold up of food coming or going. Good luck.
