In Spain, "pan de perro" is mentioned as early as 1623 in a play by Lope de Vega. It is used here in the sense of giving someone blows; to "give dog's bread" to someone could mean anything from mistreating them to killing them. The latter meaning refers to a special bread (also called zarazas) made with ground glass, poison and needles and intended to kill dogs.
Dogs of various breeds love this biscuit, so it is a handy one to bring during training. There have been no reports of allergies or adverse reactions. There were very few dogs, however, that didn’t like the treat and preferred other brands. Overall, this is one of the best healthy treats for dogs available in pet supply and online stores now that's also USDA certified.
“I think it’s helpful to think about why you’re using treats and what message you intend and what behavior you want to reinforce,” she says. “If you give treats willy-nilly all over the place for no apparent reason, that can be detrimental because you may be giving too many treats and your pet may become overweight, but you also lose the opportunity to set up certain [behavioral] expectations.”
As much as we love our four-legged friend, some of us have a tendency to spoil them a little bit, giving them treats containing ingredients that might not be that great for them. When your pup is looking at you with those puppy dog eyes, it’s difficult, if not impossible, not to spoil them a little. But, with spoiling, comes the importance of providing healthy dog treats, instead of treats filled with calories and unhealthy ingredients.
